Subject: mm/memcg: fix last_dead_count memory wastage
Shorten mem_cgroup_reclaim_iter.last_dead_count from unsigned long to int:
it's assigned from an int and compared with an int, and adjacent to an
unsigned int: so there's no point to it being unsigned long, which wasted
104 bytes in every mem_cgroup_per_zone.
