ad537689c3 [SCSI] qla2xxx: Remove qla2x00_wait_for_loop_ready function.
This function can wait for 5min under certain scenarios. One of them is when
the port is down from switch and bus reset is issued. The bus reset used to
wait for 5 minutes for the loop and upper layer callers used to hang and give
stack trace because of getting stuck for 120 sec. It is legacy code that was
used when the driver used to do queuing of the commands.

d424754cbe [SCSI] qla2xxx: Correct inadvertent clearing of RISC_INTR status.
During heavy I/O (CPU-affinity mode enabled) and CLI/Agent
interactions, the driver would report periodic mailbox command
timeout statuses.  Within the CPU-affinity ISR handler, the
driver should check the 'disable-msix-handshake' flag in deciding
whether or not to clear HCCRX_CLR_RISC_INT.  The mode is not
specific to a dedicated queue, instead, applies to the current
'ha' context.

9bfacd01dc [SCSI] qla2xxx: Fix crash in qla2x00_abort_all_cmds() on unload
I hit a crash in qla2x00_abort_all_cmds() if the qla2xxx module is
unloaded right after it is loaded.  I debugged this down to the abort
handling improperly treating a command of type SRB_ADISC_CMD as if it
had a bsg_job to complete when that command actually uses the iocb_cmd
part of the union.  (I guess to hit this one has to unload the module
while the async FC initialization is still in progress)

It seems we should only look for a bsg_job if type is SRB_ELS_CMD_RPT,
SRB_ELS_CMD_HST or SRB_CT_CMD, so switch the test to make that explicit.
