ALSA: hda: Fix regression of hdmi eld control created based on invalid pcm
Commit fb087eaaef72 ("ALSA: hda - hdmi eld control created based on pcm")
forget to filter out invalid pcm numbers, if there is only one invalid pcm
number, then this issue causes we create eld control for invalid pcm silently,
but when there are more than one invalid pcm numbers, then this issue bring
probe error looks like below dmesg:
