ALSA: hda/cs8409: Fix Jack detection after resume

Browse Source 
The suspend code unconditionally sets ->hp_jack_in and ->mic_jack_in
to zero but without reporting this status change to the HDA core.
To compensate for this, always assume a status change on the
first unsol event after boot or resume.
