The driver would crash if it was unable to find an output route, and subsequently the destruction of controller did not invoke `GenericInterruptHandler::will_be_destroyed()` because on the level of `AudioController`, that method is unavailable. By decoupling the interrupt handling from the controller, we get a new refcounted class that correctly cleans up after itself :^)
