ASoC: wcd9335: reset the SWR_CH_CNT at session teardown



In speaker protection usecase, if SWR_CH is already
set to 2 due to bootup tone playback then the initial
calibration fails. As the WSA register writes will
fail due to gr_sid will not match with dev_num
and temperature read will return negative value.
To address this, when session teardown reset the
soundwire master channel count in tasha driver.
