hugetlb: convert hugetlb_vma_maps_page() to hugetlb_vma_maps_pfn()
pte_page() is more expensive than pte_pfn() (often it's defined as
pfn_to_page(pte_pfn())), so it makes sense to do the conversion to pfn
once (by calling folio_pfn()) rather than convert the pfn to a page each
time.
While this is a very small advantage, the main motivation is removing a
reference to folio->page.
