[PATCH 1/4] mm, page_alloc: do not report all nodes in show_mem

[Michal Hocko <mhocko@kernel.org>]

From: Michal Hocko <mhocko@suse.com>

599d0c954f91 ("mm, vmscan: move LRU lists to node") has added per numa
node statistics to show_mem but it forgot to add skip_free_areas_node
to fileter out nodes which are outside of the allocating task numa
policy. Add this check to not pollute the output with the pointless
information.
