All the VM events related statistics have dependence on
'CONFIG_VM_EVENT_COUNTERS', once any stack variable is required by any
VM events in future, we would have codes like:
  #ifdef CONFIG_VM_EVENT_COUNTERS
       unsigned long foo;
  #endif
       ...
  #ifdef CONFIG_VM_EVENT_COUNTERS
       foo = events[XXX] + events[YYY];
       update_stat(vb, idx++, VIRTIO_BALLOON_S_XXX, foo);
  #endif

Separate vm events into a single function, also remove

Why not simply use __maybe_unused for that variable?
