Instead of adding more complexity and increasing divergence between classic LRU
and MGLRU, let's fix lruvec_page_state_local for all. Usage of lruvec_lru_size
instead lruvec_page_state_local was mainly due to concern on adding upward tree
traversal on stats update side i.e. get_non_dying_memcg_[start|end].

However offlining should be rate. Let's just use get_non_dying_memcg_[start|end]
everywhere and not just v1 and measure the impact.
