Fix race condition for doze mode and wake-and-unlocking

When pulse was about to turn on and at the same time we were starting
a wake-and-unlock sequence, there was jank because the scrim handling
was not correct anymore. Now, abort the pulse when we are wake-and-
unlocking so we don't see flickering with the scrims anymore.
