[SCSI] iscsi: return data transfer residual for data-out commands

Browse Source 
Currently, the iSCSI driver returns the data transfer residual for
data-in commands (e.g. read) but not data-out commands (e.g. write).
This patch makes it return the data transfer residual for both types of
commands.
