mm/list_lru.c: revert "mm/list_lru: optimize memcg_reparent_list_lru_node()"
Commit 405cc51fc104 ("mm/list_lru: optimize memcg_reparent_list_lru_node()")
has subtle races which are proving ugly to fix. Revert the original
optimization. If quantitative testing indicates that we have a
significant problem here then other implementations can be looked at.
Fixes: 405cc51fc104 ("mm/list_lru: optimize memcg_reparent_list_lru_node()")
