asoc: wcd938x: Reset mbhc detection type after ssr

Browse Source 
During headset playback if we trigger SSR, headset removal
is not detected. This is because after recovery mbhc
driver expects a new detection event as the driver is reinitialized.
Reset detection type to insertion to retrigger a hw interrupt
for mbhc driver.
