Introduce cma_alloc_frozen{_compound}() helper to alloc pages without
incrementing their refcount, then convert hugetlb cma to use the
cma_alloc_frozen_compound() and cma_release_frozen() and remove the unused
cma_{alloc,free}_folio(), also move the cma_validate_zones() into
mm/internal.h since no outside user.
The set_pages_refcounted() is only called to set non-compound pages after
above changes, so remove the processing about PageHead.
