mm/hugetlb: change hugetlb allocation functions to return a folio

Many hugetlb allocation helper functions have now been converting to
folios, update their higher level callers to be compatible with folios. 
alloc_pool_huge_page is reorganized to avoid a smatch warning reporting
the folio variable is uninitialized.
