fs/ntfs3: provide block_invalidate_folio to fix memory leak
The ntfs3 filesystem lacks the 'invalidate_folio' method and it causes
memory leak. If you write to the filesystem and then unmount it, the
cached written data are not freed and they are permanently leaked.
Fixes: 7ba13abbd31e ("fs: Turn block_invalidatepage into block_invalidate_folio")
