mm/hugetlb: refactor unmap_hugepage_range() to take folio instead of page
The function unmap_hugepage_range() has two kinds of users:
1) unmap_ref_private(), which passes in the head page of a folio. Since
unmap_ref_private() already takes folio and there are no other uses
of the folio struct in the function, it is natural for
unmap_hugepage_range() to take folio also.
2) All other uses, which pass in NULL pointer.
In both cases, we can pass in folio. Refactor unmap_hugepage_range() to
take folio.
