Tetsuo Handa 99652ee9c5 tomoyo: Use atomic_t for statistics counter 
commit a8772fad01 upstream.

syzbot is reporting that there is a race at tomoyo_stat_update() [1].
Although it is acceptable to fail to track exact number of times policy
was updated, convert to atomic_t because this is not a hot path.
