mm/memcg: iteration skip memcgs not yet fully initialized
commit d8ad30559715ce97afb7d1a93a12fd90e8fff312 upstream.
It is surprising that the mem_cgroup iterator can return memcgs which
have not yet been fully initialized. By accident (or trial and error?)
this appears not to present an actual problem; but it may be better to
prevent such surprises, by skipping memcgs not yet online.
