ALSA: hda/realtek - Fixed ALC286/ALC288 recording delay for Headset Mic 

It will be recording voice delay for resume back recording for Headset Mic.
This alc286 will quickly open Headset Mic, to prevent avoid recording files are missing.
The issue was fixed. This is follow ALC286 programing guide.

[fix build error, add static and renamed the function by tiwai]
