target: Generate failure for XCOPY I/O with non-zero scsi_status
This patch adds the missing non-zero se_cmd->scsi_status check required for local XCOPY I/O within target_xcopy_issue_pt_cmd() to signal an exception case failure. This will trigger the generation of SAM_STAT_CHECK_CONDITION status from within target_xcopy_do_work() process context code.
