Don't check Doze state if device is in the middle of a transition

Checking the doze state in the middle of a transition
will throw an IllegalStateException.

DozeSuppresor doesn't need to update the doze state
if the doze machine is already in the middle of
executing transitions. Whenever the next doze
state is executed, DozeMachine#transitionPolicy
will make sure the device properly exits the
powerSaver AOD state (that keeps AOD off).

If a UDFPS long press is triggered while DozeMachine
is executing a transition, the pulse will be dropped,
so we don't need to set the aodInterrupt.
