Subject: [PATCH] mm: use for_each_online_cpu() in vmstat

The sum_vm_events passes cpumask for for_each_cpu().  But it's useless
since we have for_each_online_cpu.  Althougth it's tirival overhead, it's
not good about coding consistency.

Let's use for_each_online_cpu instead of for_each_cpu with cpumask
argument.
