mm, memcg: clean up reclaim iter array
The mem_cgroup_reclaim_cookie is only used in memcg softlimit reclaim now, and the priority of the reclaim is always 0. We don't need to define the iter in struct mem_cgroup_per_node as an array any more. That could make the code more clear and save some space.
