memcg: make mod_memcg_state re-entrant safe against irqs
Let's make mod_memcg_state 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.
mod_memcg_state() is not safe against nmi, so let's add warning if someone
tries to call it in nmi context.
