target: Don't override EXTENDED_COPY xcopy_pt_cmd SCSI status code
This patch addresses a bug where a local EXTENDED_COPY WRITE or READ backend I/O request would always return SAM_STAT_CHECK_CONDITION, even if underlying xcopy_pt_cmd->se_cmd generated a different SCSI status code. ESX host environments expect to hit SAM_STAT_RESERVATION_CONFLICT for certain scenarios, and SAM_STAT_CHECK_CONDITION results in non-retriable status for these cases. Tested on v4.1.y with ESX v5.5u2+ with local IBLOCK backend copy.
