Not all code in the block layer uses the SCSI error codes. Do we need
code to convert negative error codes into a SCSI error code here ? An
example:

void blk_mq_abort_requeue_list(struct request_queue *q)
{
        [ ... ]
                rq->errors = -EIO;
        [ ... ]
}
EXPORT_SYMBOL(blk_mq_abort_requeue_list);
