scsi: mpi3mr: NVMe command size greater than 8K fails
[ Upstream commit 4f297e856a7b5da2f2c66a12e739666e23943560 ]
A wrong variable is checked while populating PRP entries in the PRP page
and this results in failure. No PRP entries in the PRP page were
successfully created and any NVMe Encapsulated commands with PRP of size
greater than 8K failed.
