ASoC: wcd: correct reporting of unsupported cable

If unsupported cable is slowly inserted it can be detected as
headset/headphone initially and then as unsuported cable.
Due to this MBHC driver is reporting headset/headphone first and
then unsupported cable, due to which headset icon is displayed.
So report removal of headset/headphone while reporting insertion
of unsupported cable.
