block: add a bio_add_virt_nofail helper
[ Upstream commit 850e210d5ad21b94b55b97d4d82b4cdeb0bb05df ]
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.
