mm: memcontrol: push down mem_cgroup_node_nr_lru_pages()
mem_cgroup_node_nr_lru_pages() is just a convenience wrapper around lruvec_page_state() that takes bitmasks of lru indexes and aggregates the counts for those. Replace callsites where the bitmask is simple enough with direct lruvec_page_state() calls. This removes the last extern user of mem_cgroup_node_nr_lru_pages(), so make that function private again, too.
