scsi: mpi3mr: Add NULL checks when resetting request and reply queues

Browse source

[ Upstream commit fa96392ebe ]

The driver encountered a crash during resource cleanup when the reply and
request queues were NULL due to freed memory.  This issue occurred when the
creation of reply or request queues failed, and the driver freed the memory
first, but attempted to mem set the content of the freed memory, leading to
a system crash.

Add NULL pointer checks for reply and request queues before accessing the
reply/request memory during cleanup
