Noticed that I wasn't paying close enough attention the last time I looked at our audio callbacks, as I completely missed the fact that we were figuring out which audio-enabled connector goes to each encoder by checking it's state, but without grabbing any of the appropriate modesetting locks to do so. That being said however: trying to grab modesetting locks in our audio callbacks would be very painful due to the potential for locking inversion between HDA and DRM. So, let's instead just copy what i915 does again - add our own audio lock to protect audio related state, and store each audio enabled connector in each nouveau_encoder struct so that we don't need to check any atomic states.
