block: provide bio_clear_hipri() helper
Any case that turns off REQ_HIPRI must also clear BIO_PERCPU_CACHE,
as non-polled IO may complete through hard/soft IRQ and hence isn't
safe for our polled bio alloc cache.
Provide a helper that does just that, and use it in the merging code as
well if we split a bio and turn off polling.
Fixes: be863b9e4348 ("block: clear BIO_PERCPU_CACHE flag if polling isn't supported")
