scsi: mpi3mr: Fix reporting of actual data transfer size

Browse source 
[ Upstream commit 9992246127 ]

The driver is missing to set the residual size while completing an
I/O. Ensure proper data transfer size is reported to the kernel on I/O
completion based on the transfer length reported by the firmware.
