We must call shrink_slab() for each memory cgroup on both global and memcg reclaim in shrink_node_memcg(). Commit d71df22b55099 accidentally changed that so that now shrink_slab() is only called with memcg != NULL on memcg reclaim. As a result, memcg-aware shrinkers (including dentry/inode) are never invoked on global reclaim. Fix that.
