ASoC: wcd938x: Fix event generation for some controls
Currently wcd938x_*_put() unconditionally report that the value of the
control changed, resulting in spurious events being generated. Return 0 in
that case instead as we should. There is still an issue in the compander
control which is a bit more complex.
