ASoC: adau17x1: remove unused ‘ret’

Browse source 
In adau17x1_pll_event(), 'ret' is initialized as return value of
regmap_raw_write() but never checked, so remove this and assignement.

sound/soc/codecs/adau17x1.c: In function ‘adau17x1_pll_event’:
sound/soc/codecs/adau17x1.c:68:6: warning: variable ‘ret’ set but not used [-Wunused-but-set-variable]
  int ret;
