Cezary Rojewski e7255c00b1 ALSA: hda: Skip event processing for unregistered codecs 
When codec is unbound but not yet removed, in the eyes of
snd_hdac_bus_process_unsol_events() it is still a valid target to
delegate work to. Such behaviour may lead to use-after-free errors.
Address by verifying if codec is actually registered.
