ceph: check folio PG_private bit instead of folio->private

The pages in the file mapping maybe reclaimed and reused by other
subsystems and the page->private maybe used as flags field or
something else, if later that pages are used by page caches again
the page->private maybe not cleared as expected.

Here will check the PG_private bit instead of the folio->private.
