 - Do not take memcg_limit_mutex for resetting limits - the cgroup
   cannot be altered from userspace anymore, so no need to protect them.

 - Use plain page_counter_limit() for resetting ->memory and ->memsw
   limits instead of mem_cgrouop_resize_* helpers - we enlarge the
   limits, so no need in special handling.

 - Reset ->swap and ->tcpmem limits as well.
