Subject: mm: memcontrol: fix possible memcg leak due to interrupted reclaim fix
When we handled multiple css references in mem_cgroup_iter() it got a
little confusing which puts belong to which gets. Now that we only ref
the position css it's obvious, and a multi-line comment to explain it
gets in the way of reading an already long function.
