xfs: cleanup mapping tmpfs folios into the buffer cache
Directly assign b_addr based on the tmpfs folios without a detour
through pages, reuse the folio_put path used for non-tmpfs buffers
and replace all references to pages in comments with folios.
Partially based on a patch from Dave Chinner <dchinner@redhat.com>.
