hugetlb: remove a few calls to page_folio()
Anything found on a linked list threaded through ->lru is guaranteed to be
a folio as the compound_head found in a tail page overlaps the ->lru
member of struct page. So we can pull folios directly off these lists no
matter whether pages or folios were added to the list.
