ASoC: wcd-mbhc: Avoid fake headset report during headphone remove
When headphone is removed while 3 second polling is still in progress,
mbhc hs comparator result will be read as "0" and this causes reporting
a fake headset insert event to user-space followed by headphone removal.
Avoid sending this fake headset insert event to user-space by checking
for the microphone clamp bit from codec mbhc hardware.
