Remove obsolete scrim transition

Scrim transitions should only be orchestrated by the StatusBar.

This method call should never be here, StatusBar#updateScrimController()
already does all the necessary work.

Test: Unlock with fingerprint, observe scrims.
Test: Touch fingerprint sensor after reboot, look at bouncer.
