Fix Wear brightness after tilt-to-wake

When performing a tilt-to-wake gesture on a Wear device, if the offload session fails, the policy is POLICY_DOZE but the screen state is STATE_ON.

The doze scale factor shouldn't be applied if the screen is on.

The initial doze brightness or the default doze brightness shouldn't be used if the screen is on.
