Subject: [PATCH 6/6] mm/z3fold: use release_z3fold_page_locked() to release locked z3fold page

We should use release_z3fold_page_locked() to release z3fold page when it's
locked, although it looks harmless to use release_z3fold_page() now.

Fixes: dcf5aedb24f8 ("z3fold: stricter locking and more careful reclaim")
