This patch renames the flag for indicating host reset from
ioc_reset_in_progress to shost_recovery. It also removes the spin locks
surrounding the setting of this flag, which are unnecessary. Sanity checks on
the shost_recovery flag were added thru out the code so as to prevent sending
firmware commands during host reset. Also, the setting of the shost state to
SHOST_RECOVERY was removed to prevent deadlocks, this is actually better
handled by the shost_recovery flag.

Following host reset its possible that the controller firmware could
assign new handles for devices, as well as adding or deleting devices. There is
code in the driver that will rescan the topology folowing host reset; updating
device handles, and remove devices that are no longer responding. This patch
will improve the responsivness by moving this rescaning from the delayed hotplug
worker thread to immediately following the host reset.

Fix oops ocurring at hibernation time. This oops was due to the firmware fault
watchdog timer still running after we freed resources. To fix the issue we need
to terminate the watchdog timer at hibernation time.

[SCSI] mpt2sas : bump driver version to 01.100.02.00
The MPT2SAS_MAJOR_VERSION didn't get bumped from 00 to 01 so
applications will see it incorrectly as 00.100.02.00 driver instead of
01.100.02.00. Fix by making MPT2SAS_MAJOR_VERSION match the major
number in MPT2SAS_DRIVER_VERSION

The Dell branding along with the VID, DID, SSVID, SSDID following the LSI
branding that contains the card firmware/chip/bios versions. If the SSDID
is not known but it is a Dell HBA, the driver will print the SSDID instead
of the Dell branding string. Nothing will be printed for non Dell HBAs

The ioc_list global symbol is already used in 1st generation mpt
fusion drivers, so this patch makes it unique in the 2nd generation
driver. I've checked the entire sources, and I don't see any other
global system missing the mpt2sas_xxx prefix.
