KAMEZAWA Hiroyuki 3eae90c3cd 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.
