mm: hugetlb: fix pgoff computation when unmapping page from vma
The computation for pgoff is incorrect, at least with
(vma->vm_pgoff >> PAGE_SHIFT)
involved. It is fixed with the available method if HPAGE_SIZE is
concerned in page cache lookup.
[akpm@linux-foundation.org: use vma_hugecache_offset() directly, per Michal]
