ASoC: codecs: wcd938x: fix return value of mixer put function

commit bd2347fd67d8da0fa76296507cc556da0a233bcb upstream.

wcd938x_ear_pa_put_gain, wcd938x_set_swr_port and  wcd938x_set_compander
currently returns zero eventhough it changes the value.
Fix this, so that change notifications are sent correctly.
