ASoC: msm8x10-wcd: Do not disable micbias when TX path is ON
Insert headset after initiating voice call and then force switch
to speaker mode.In this case if headset is removed, we are disabling
micbias which is resulting in TX path mute.So check whether TX path is
active before powering down micbias
