wov: Modify wov_set_gain to update gain params in wov_conf
The function wov_set_gain would only pass along the desired channel
gain values to the apm, but did not update channel gain parameters of
wov_conf. This CL modifies this function to also update those
parameters so they can be saved an retrieved by the audio codec.
