Vladimir Davydov b5afba2974 mm: vmscan: fix memcg-aware shrinkers not called on global reclaim ...

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.

Fixes: b2e18757f2c9 ("mm, vmscan: begin reclaiming pages on a per-node basis")
