    os: return 0 from check_timers if we touched any of them
    
    Fixes a regression introduced in 0b2f30834b1a9f. If a driver posts input
    events during a timer function (wacom and synaptics do this during tap
    timeouts), ProcessInputEvents() is not called for these events. There are no
    new events on any fds, so the events just sit in the queue waiting for
    something else to happen.
    
    Fix this by simply returning 0 from check_timers if we ran at least one of
    them or reset them all. This way the callers ospoll_wait will exit and
    continue with normal processing.
