sync: schedule a wakeup if we're called on the positive transition
Complement to a2e67a6412386782cb8b644b86a5744591397d45 which handled this for
the negative transition case. If we have an alarm on a positive transition on
the idletimer and get called exactly on the trigger, schedule a wakeup for a
ms.
