Is it possible for the snd_jack object to own its kctls, so when 
snd_jack_dev_free is called, that would free the kctls too? Or at least 
have some kind of flag that would allow snd_jack_free to also delete its 
associated kctls?

(And then snd_hda_codec_reset/free would end up calling snd_jack_dev_free.)
