hugetlb: convert alloc_buddy_hugetlb_folio to use a folio

While this function returned a folio, it was still using __alloc_pages()
and __free_pages().  Use __folio_alloc() and put_folio() instead.  This
actually removes a call to compound_head(), but more importantly, it
prepares us for the move to memdescs.
