target: Don't override EXTENDED_COPY xcopy_pt_cmd SCSI status code
commit 926317de33998c112c5510301868ea9aa34097e2 upstream.
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.
