memcg: make count_memcg_events re-entrant safe against irqs
Let's make count_memcg_events re-entrant safe against irqs. The only
thing needed is to convert the usage of __this_cpu_add() to
this_cpu_add(). In addition, with re-entrant safety, there is no need to
disable irqs. Also add warnings for in_nmi() as it is not safe against
nmi context.
