ovl: whiteout orphan index entries on mount
Orphan index entries are non-dir index entries whose union nlink count dropped to zero. With index=on, orphan index entries are removed on mount. With NFS export feature enabled, orphan index entries are replaced with white out index entries to block future open by handle from opening the lower file. When dir index has a stale 'upper' xattr, we assume that the upper dir was removed and we treat the dir index as orphan entry that needs to be whited out or removed.
