ALSA: hda - No loopback on ALC299 codec

Browse Source 
[ Upstream commit fa16b69f1299004b60b625f181143500a246e5cb ]

ALC299 has no loopback mixer, but the driver still tries to add a beep
control over the mixer NID which leads to the error at accessing it.
This patch fixes it by properly declaring mixer_nid=0 for this codec.
