ALSA: hda - Allow one chance for zero NID in connection list
The commit [2e9bf24: ALSA: hda_codec: Check for invalid zero connections] trims the whole connection list when an invalid value is reported by the hardware. But some codecs (at least AD1986A) may give a zero NID in the middle of the connection list, so dropping the whole list isn't good for such cases.

ALSA: hda - Increase the max depth of widget connections
Old codecs like AD1986A tend to have long paths as they were just made to be the way like AC97. The current max depth 5 can be too short for such devices.
