[PATCH 5.12 671/700] mm/z3fold: use release_z3fold_page_locked() to release locked z3fold page

[Greg Kroah-Hartman]

From: Miaohe Lin <linmiaohe@xxxxxxxxxx>

[ Upstream commit 28473d91ff7f686d58047ff55f2fa98ab59114a4 ]

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.
