[SCSI] Ensure discard failure gets treated as a target problem
The error reported up the stack for a discard failure did not clearly indicate that the command was processed and subsequently failed by the target device. Return -EREMOTEIO so multipathing does not classify this condition as a path failure. Signed-off-by: Martin K.
