scsi: ufs: core: Set the residual byte count
It is important for the SCSI core to know the residual byte count. Hence,
extract the residual byte count from the UFS response and pass it to the
SCSI core. A few examples of the output of a debugging patch that has been
applied on top of this patch:
[ 1.937750] cmd 0x12: len = 255; resid = 241
[ ... ]
[ 1.993400] cmd 0xa0: len = 4096; resid = 4048
[ ... ]
