ASoC: wcd9335: Avoid TX mute during voice call on headset 



If long button is pressed to end the voice call, the button
click suppression block within wcd9335 hardware does not
release IN2_P causing TX mute for the next voice call session.
Avoid TX mute by force release IN2_P during every voice call
start.
