mm/memcontrol.c: remove redundant BUG_ON() in mem_cgroup_usage_unregister_event() 

In the following code:

	if (type == _MEM)
		thresholds = &memcg->thresholds;
	else if (type == _MEMSWAP)
		thresholds = &memcg->memsw_thresholds;
	else
		BUG();

	BUG_ON(!thresholds);

The BUG_ON() seems redundant.
