From: Johannes Thumshirn <johannes.thumshirn@xxxxxxx>
When the iomap buffered-io code can't add a folio to a bio, it allocates a
new bio and adds the folio to that one. This is done using bio_add_folio(),
but doesn't check for errors.
As adding a folio to a newly created bio can't fail, use the newly
introduced __bio_add_folio() function.
