mm/hugetlb: convert hugetlb_change_protection() to folios
The for loop inside hugetlb_change_protection() increments by the huge
page size:
psize = huge_page_size(h);
for (; address < end; address += psize)
so we are operating on the head page of the huge pages between address and
end. We can safely convert the struct page usage to struct folio.
