Subject: ALSA: hda - Gate the mic jack on HP Z1 Gen3 AiO

From: Takashi Iwai <tiwai@suse.de>

commit f73cd43ac3b41c0f09a126387f302bbc0d9c726d upstream.

HP Z1 Gen3 AiO with Conexant codec doesn't give an unsolicited event
to the headset mic pin upon the jack plugging, it reports only to the
headphone pin.  It results in the missing mic switching.  Let's fix up
by simply gating the jack event.
