ASoC: wcd938x: Fix headset detection during SSR/PDR

Browse source 
Headset is corrected as lineout during SSR/PDR. This is
because adc voltage is not measured correctly due to SSR state.
Enable flag deinit_in_progress during SSR down to check if
device is not reported and disable it after device up.
