ALSA: hda/realtek - Skip invalid digital out pins
commit 51e4152a969aa6d2306492ebf143932dcb535c9b upstream. Some BIOS report invalid pins as digital output pins. The driver checks the connection but it doesn't do it fully correctly, and it leaves some undefined value as the audio-out widget, which makes the driver spewing warnings. This patch fixes the issue.
