filemap: update offset check in filemap_fault()

Update it to: VM_BUG_ON_PAGE(page_to_pgoff(page) != offset, page); Link: http://lkml.kernel.org/r/20190801184244.3169074-4-songliubraving@fb.com Signed-off-by: Song Liu <songliubraving@fb.com> Acked-by: Rik van Riel <riel@surriel.com> Acked-by: Kirill A.
