memcg: remove redundant function calls
remove_list/add_list uses page_cgroup_zoneinfo() in it.
So, it's called twice before and after lock.
mz = page_cgroup_zoneinfo();
lock();
mz = page_cgroup_zoneinfo();
....
unlock();
And address of mz never changes.
This is not good. This patch fixes this behavior.
