target: Fix handling of aborted failed commands
If a target driver (e.g. tcm_qla2xxx) calls transport_generic_request_failure() to report that receiving data has failed and that SCSI command has already been aborted by the initiator, ensure that the SCSI status ABORTED is sent back to the initiator instead of the sense code provided by the target driver.
