memcg: do obj_cgroup_put inside drain_obj_stock
Previously we could not call obj_cgroup_put() inside the local lock
because on the put on the last reference, the release function
obj_cgroup_release() may try to re-acquire the local lock. However that
chain has been broken. Now simply do obj_cgroup_put() inside
drain_obj_stock() instead of returning the old objcg.
