target: Change TCM_NON_EXISTENT_LUN response to ASC=LOGICAL UNIT NOT SUPPORTED
This patch changes transport_send_check_condition_and_sense() for TCM_NON_EXISTENT_LUN emulation to use 0x25 (LOGICAL UNIT NOT SUPPORTED) instead of the original 0x20 (INVALID COMMAND OPERATION CODE). This is helpful to distinguish between TCM_UNSUPPORTED_SCSI_OPCODE ASC=0x20 exceptions. Signed-off-by: Nicholas A. Bellinger <nab@risingtidesystems.com>
