[RFC PATCH 4/7] ALSA: hda/hdmi - allow control creation without a linked pcm

[Kai Vehmanen <kai.vehmanen@linux.intel.com>]

Fix the logic in generic_hdmi_build_controls() to identify
unused hda_pcm entries by searching for SNDRV_PCM_INVALID_DEVICE.
This matches with logic in snd_hda_codec_build_pcms().
