hugetlb: create hugetlb_unmap_file_folio to unmap single file folio
Create the new routine hugetlb_unmap_file_folio that will unmap a single
file folio. This is refactored code from hugetlb_vmdelete_list. It is
modified to do locking within the routine itself and check whether the
page is mapped within a specific vma before unmapping.
This refactoring will be put to use and expanded upon in a subsequent
patch adding vma specific locking.
