Peter Ujfalusi 1c7f0e349a ALSA: hda: Skip codec shutdown in case the codec is not registered 
If the codec->registered is not set then it means that pm_runtime is
not yet enabled and the codec->pcm_list_head has not been initialized.

The access to the not initialized pcm_list_head will lead a kernel crash
during shutdown.
