ALSA: pcm: Don't ignore internal PCMs in snd_pcm_dev_disconnect()
Some codes in snd_pcm_dev_disconnect() are still valid even for
internal PCMs, but they are skipped because of the check of
list_empty(&pcm->list) at the beginning. Remove this check and put
pcm->internal checks appropriately for internal PCM object to process
through this function.
