scsi: mpi3mr: Fix the type used for pointers to bitmap

BugLink: https://bugs.launchpad.net/bugs/2029905

Bitmaps are "unsigned long[]", so better use "unsigned long *" instead of a
plain "void *" when dealing with pointers to bitmaps.

This is more informative.

scsi: mpi3mr: Use IRQ save variants of spinlock to protect chain frame allocation

BugLink: https://bugs.launchpad.net/bugs/2029905

Driver uses spin lock without irqsave when it needs to acquire a chain
frame. This is done to protect chain frame allocation from multiple
submission threads. If there is any I/O queued from an interrupt context,
and if that requires a chain frame, and if the chain lock is held by the CPU
which got interrupted, then there will be a possible deadlock.

scsi: mpi3mr: Handle soft reset in progress fault code (0xF002)

BugLink: https://bugs.launchpad.net/bugs/2029905

The driver is exiting from the fault watchdog thread if it sees the 0xF002
(Soft reset in progress) fault code.

If the driver initiates the soft reset, then the driver restarts the
watchdog at the end of the soft reset completion. However, if the soft
reset is initiated by the firmware asynchronously, then the driver will
never restart the watchdog and never re-initialize the controller after the
asynchronous soft reset completion.
