Christoph Hellwig cef2315cb8 block: add a bio_add_virt_nofail helper ...

[ Upstream commit 850e210d5a ]

Add a helper to add a directly mapped kernel virtual address to a
bio so that callers don't have to convert to pages or folios.

For now only the _nofail variant is provided as that is what all the
obvious callers want.
