Fix Panel position may not update when device screen off / on quickly.

Due to framework side will not callback onScreenTurningOn() when device screen off / on quickly,
So NotificationPanel will not called onScreenTurningOn to update panel position.

There is also a potential issue for cancel touch will be ignored when touch disable
in onFinishedGoingToSleep().

Let ACTION_CANCEL can pass even touch disable to recover Panel position by fling back.
