Series memcg: reduce memory consumption by memcg stats | expand

Commit Message

WORKINGSET_NODES is not exposed in the memcg stats and thus there is no
need to use the memcg specific stat update functions for it. In future
if we decide to expose WORKINGSET_NODES in the memcg stats, we can
revert this patch.
