Periodic timers are broken, because the also only fire once. As it happens, Linux doesn't care because it only sets the timer to periodic very briefly during boot, and then switches it only between one-shot and off later. Nevertheless, fix the logic (we shouldn't even be looking at time_travel_timer_expiry unless the timer is enabled) and change the code to fire the timer periodically in periodic mode, in case it ever gets used in the future.
