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")
