blk-mq: fix filesystem I/O request allocation
submit_bio_checks() may update bio->bi_opf, so we have to initialize
blk_mq_alloc_data.cmd_flags with bio->bi_opf after submit_bio_checks()
returns when allocating new request.
In case of using cached request, fallback to allocate new request if
cached rq isn't compatible with the incoming bio, otherwise change
rq->cmd_flags with incoming bio->bi_opf.
Fixes: 900e080752025f00 ("block: move queue enter logic into blk_mq_submit_bio()")
