Vladimir Davydov 615d66c37c mm: memcontrol: fix memcg id ref counter on swap charge move
Since commit 73f576c04b ("mm: memcontrol: fix cgroup creation failure
after many small jobs") swap entries do not pin memcg->css.refcnt
directly.  Instead, they pin memcg->id.ref.  So we should adjust the
reference counters accordingly when moving swap charges between cgroups.

Fixes: 73f576c04b ("mm: memcontrol: fix cgroup creation failure after many small jobs")
