Description:
- Cancel the interval timer and return the time remaining on the timer. These two steps need to be as nearly atomic as possible.up_timer_expiration() will not be called unless the timer is restarted with up_timer_start(). If, as a race condition, the timer has already expired when this function is called, then that pending interrupt must be cleared so that up_timer_expiration() is not called spuriously and the remaining time of zero should be returned.
