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]

The read can be removed at the same time.
