memcg: change try_to_free_pages to hierarchical_reclaim
mem_cgroup_hierarchicl_reclaim() works properly even when !use_hierarchy
now (by memcg-hierarchy-avoid-unnecessary-reclaim.patch), so, instead of
try_to_free_mem_cgroup_pages(), it should be used in many cases.
The only exception is force_empty. The group has no children in this
case.
