Four driver fixes and one core fix. The core fix closes a race window
where we could kick off a second asynchronous scan because the test

The code to try to shut up sparse warnings about questionable locking
didn't shut up sparse: it made the result not parse as valid C at all,
since the end result now has a label with no statement.
The proper fix is to just always lock the hardware, the same way Bart
did in commit 8ae178760b ("scsi: qla2xxx: Simplify the functions for
dumping firmware"). That avoids the whole problem with having locking
that is not statically obvious.
But in the meantime, just remove the incorrect attempt at trying to
avoid a sparse warning that just made things worse.
This was exposed by commit 3e6efab865 ("scsi: qla2xxx: Fix reset of
MPI firmware"), very similarly to how commit cbb01c2f2f ("scsi:
qla2xxx: Fix MPI failure AEN (8200) handling") exposed the same problem
in another place, and caused that commit 8ae178760b.
Please don't add code to just shut up sparse without actually fixing
what sparse complains about.

When the fcport is about to be deleted we should return EBUSY instead of
ENODEV. Only for EBUSY will the request be requeued in a multipath setup.
Also return EBUSY when the firmware has not yet started to avoid dropping
the request.

The set of core changes here is Christoph's submission path cleanups.
These introduced a couple of regressions when first proposed so they
got held over from the initial merge window pull request to give more
testing time, which they've now had and Syzbot has confirmed the
regression it detected is fixed. The other main changes are two
driver updates (arcmsr, pm80xx) and assorted minor clean ups.

Normally, the MPI firmware is reset when an MPI dump is collected. If an
unsaved MPI dump exists in the driver, though, an alternate mechanism is
used. This mechanism, which was not fully correct, is not recommended and
instead an MPI dump template walk is suggested to perform the MPI reset.
To allow for the MPI dump template walk, extra space is reserved in the MPI
dump buffer which gets used only when there is already an MPI dump in
place.

It was observed on an ISP8324 16Gb HBA with fw=8.08.203 (d0d5) in a
PowerPC64 machine that pkt->entry_type was MBX_IOCB_TYPE/0x39 with an
sp->type SRB_SCSI_CMD which is invalid and should not be possible.
Reading the entry_type from the crash dump shows the expected value of
STATUS_TYPE/0x03 but the call trace shows that qla24xx_mbx_iocb_entry() is
used.
Add a check to verify for consistency and reset the HBA if an invalid state
is reached. Obviously, this is only a workaround until the real problem is
solved.

Refactor qla2x00_get_sp_from_handle() to avoid the unnecessary goto if
early returns are used. With this we can also avoid preinitialzing the sp
pointer.

Emit a warning when ->done or ->free are called on an already freed
srb. There is a hidden use-after-free bug in the driver which corrupts
the srb memory pool which originates from the cleanup callbacks.
An extensive search didn't bring any lights on the real problem. The
initial fix was to set both pointers to NULL and try to catch invalid
accesses. But instead the memory corruption was gone and the driver
didn't crash. Since not all calling places check for NULL pointer, add
explicitly default handlers. With this we workaround the memory
corruption and add a debug help.

Eleven fixes, mostly in drivers or minor fixes in driver related
infrastructure libraries (target, libfc and libsas). Most of the bugs
fixed only show up under rare circumstances, the exception being the
endianness problem in qla2xxx which is used as a device on some sparc
systems.

Commit 98aee70d19 ("qla2xxx: Add endianizer to max_payload_size
modifier.") in 2014 broke qla2xxx on sparc64, e.g. as in the Sun Blade 1000
/ 2000. Unbreak by partial revert to fix endianness in nvram firmware
default initialization. Also mark the second frame_payload_size in nvram_t
__le16 to avoid new sparse warnings.

think this is a typo error. It is necessary to return an error value.
