memcg: fix oom killing a child process in an other cgroup
Presently the oom-killer is memcg aware and it finds the worst process
from processes under memcg(s) in oom. Then, it kills victim's child
first.
It may kill a child in another cgroup and may not be any help for
recovery. And it will break the assumption users have.
This patch fixes it.
