ASoC: codecs: tas2780: remove redundant assignments to variable ret

Variable ret is being assigned a value that is never read in a couple
of places. The variable is being re-assigned later on. The assignments
are redundant and can be removed.

Cleans up clang scan build warning:
sound/soc/codecs/tas2780.c:84:2: warning: Value stored to 'ret' is
never read [deadcode.DeadStores]
