target: Fix cmd size for PR-OUT in passthrough_parse_cdb
The cmd size should be 4bytes form byte5 to byte8 when CDB opcode is PERSISTENT_RESERVE_OUT in SPC3 and SPC4 (Also fix up the same in spc_parse_cdb - MNC) Signed-off-by: Tang Wenji <tang.wenji@zte.com.cn> Signed-off-by: Nicholas Bellinger <nab@linux-iscsi.org>
