[PATCH V2 1/2] memcg: rename mem_cgroup_zone_nr_pages() to mem_cgroup_zone_nr_lru_pages()

[Ying Han <yinghan@google.com>]

The caller of the function has been renamed to zone_nr_lru_pages(), and this
is just fixing up in the memcg code. The current name is easily to be mis-read
as zone's total number of pages.

This patch is based on mmotm-2011-05-06-16-39

no change on this patch from v1.
