P18 or other high-performance devices shouldn't use per-memcg so it was disabled on those devices[1]. However, we didn't turn off for system_server memcg so those devices still have two seperate LRU groups which would have less efficient memory reclaim. Therefore, this patch makes memcg use for system_server only if per_app_memcg is enabled.
