fs: Turn page_offset() into a wrapper around folio_pos()
This is far less efficient for the lagging filesystems which still
use page_offset(), but it removes an access to page->index. It also
fixes a bug -- if any filesystem passed a tail page to page_offset(),
it would return garbage which might result in the filesystem choosing
to not writeback a dirty page. There probably aren't any examples
of this, but I can't be certain.
