    ms/target: Use correct SCSI status during EXTENDED_COPY exception
    ML: 0583c261e6325f392c1f7a1b9112e31298e1a4bd
    This patch adds the missing target_complete_cmd() SCSI status
    parameter change in target_xcopy_do_work(), that was originally
    missing in commit 926317de33.
    It correctly propigates up the correct SCSI status during
    EXTENDED_COPY exception cases, instead of always using the
    hardcoded SAM_STAT_CHECK_CONDITION from original code.
    This is required for ESX host environments that expect to
    hit SAM_STAT_RESERVATION_CONFLICT for certain scenarios,
    and SAM_STAT_CHECK_CONDITION results in non-retriable
    status for these cases.
