ASoC: wcd9xxx: Don't enable micbias if headset is removed

Browse source 
If special headset is removed, the callback to
disable micbias will be called, as micbias is
always on with special headset. Mbhc driver
checks a flag, used to disable/enable micbias
for special headset, to make sure micbias is
not disabled by recording. If this flag is not
updated properly before the callback is called
while the headset is removed, it can cause that
micbias is left enabled.
