ASoC: tas2562: Propagate the error in tas2562_dac_event() 

Since commit 2848d34c3b ("ASoC: tas2562: Fix mute/unmute") the
following build warning is seen:

sound/soc/codecs/tas2562.c:442:13: warning: variable 'ret' set but not used [-Wunused-but-set-variable]

Fix the warning by returning the 'ret' variable.
