mm/memcontrol.c:mem_cgroup_select_victim_node(): clarify comment

> The comment seems to have not much to do with the code?

I guess the comment tries to say that the code path is triggered when we
charge the page which happens _before_ it is added to the LRU list and
so last_scanned_node might contain the stale data.
