hugetlb_vmemmap: use folio argument for hugetlb_vmemmap_* functions

Most function calls in hugetlb.c are made with folio arguments.  This
brings hugetlb_vmemmap calls inline with them by using folio instead of
head struct page.  Head struct page is still needed within these
functions.

The set/clear/test functions for hugepages are also changed to folio
versions.
