mm: huge_memory: use folio_can_map_prot_numa() for pmd folio

The folio_can_map_prot_numa() checks whether the folio can map prot numa,
which skips unsuitable folio, i.e.  zone device, shared folios (KSM, CoW),
non-movable dma pinned, dirty file folio and folios that already have the
expected node affinity.  Although the ksm only applies to small folios, an
extra test was added for large folios, but the other policies should be
applied to pmd folio, which helps to avoid unnecessary pmd change and
folio migration attempts.
