[PATCH v3 09/13] ASoC: ti: omap-mcbsp-st: Remove set, but unused variable 'w'

[Pierre-Louis Bossart]

From: Lee Jones <lee.jones@linaro.org>

Looks like 'w' has remained unchecked since the driver's inception.

Fixes the following W=1 kernel build warning(s):

 sound/soc/ti/omap-mcbsp-st.c: In function ‘omap_mcbsp_st_chgain’:
 sound/soc/ti/omap-mcbsp-st.c:145:6: warning: variable ‘w’ set but not used [-Wunused-but-set-variable]

Peter suggested that the whole read can be removed, so that's
been done too.
