mm: remove is_longterm_pinnable_page() and reimplement folio_is_longterm_pinnable()
folio_is_longterm_pinnable() already exists as a wrapper function. Now
that the whole implementation of is_longterm_pinnable_page() can be
implemented using folios, folio_is_longterm_pinnable() can be made its own
standalone function - and we can remove is_longterm_pinnable_page().
