block: Fix two comments that refer to .queue_rq() return values
Since patch "blk-mq: switch .queue_rq return value to blk_status_t" .queue_rq() returns a BLK_STS_* value instead of a BLK_MQ_RQ_* value. Hence refer to the former in comments about .queue_rq() return values. Fixes: commit 39a70c76b89b ("blk-mq: clarify dispatch may not be drained/blocked by stopping queue") Signed-off-by: Bart Van Assche <bart.vanassche@wdc.com> Reviewed-by: Hannes Reinecke <hare@suse.com> Cc: Ming Lei <ming.lei@redhat.com> Cc: Christoph Hellwig <hch@lst.de> Cc: Johannes Thumshirn <jthumshirn@suse.de> Signed-off-by: Jens Axboe <axboe@kernel.dk>
