mm/hugetlb: pass folio instead of page to unmap_ref_private()

Browse Source 
Patch series "Let unmap_hugepage_range() and several related functions
take folio instead of page", v4.


This patch (of 4):

unmap_ref_private() has only a single user, which passes in &folio->page. 
Let it take the folio directly.
