Add NR_BALLOON_PAGES counter to track memory used by balloon drivers and
expose it through /proc/meminfo and other memory reporting interfaces.
In balloon_page_enqueue_one(), we perform a
__count_vm_event(BALLOON_INFLATE)
and in balloon_page_list_dequeue
__count_vm_event(BALLOON_DEFLATE);
Should we maybe simply do the per-node accounting similarly there?
