[PATCH 2/2] ASoC: codecs: wcd938x: fix uninitialized symbol warnings

[Srinivas Kandagatla <srinivas.kandagatla@linaro.org>]

This patch fixes below two uninitialized symbol warnings

warning:
	sound/soc/codecs/wcd938x.c:2092 wcd938x_tx_swr_ctrl()
	error: uninitialized symbol 'rate'

	sound/soc/codecs/wcd938x.c:2189 wcd938x_tx_channel_config()
	error: uninitialized symbol 'reg'.

First one my brining in check to already existing if condition and
second one by adding a default switch case to avoid any access to reg.
