It would be nice to fix the overly long line while you're at it.

But looking at the two callers of blk_mq_poll, shouldn't one use
rq->mq_hctx to get the hctx anyway instead of doing repeated
blk_qc_to_hctx in the polling loop? We could then just open code
blk_qc_to_hctx in the remaining one.
The rest looks good to me.
