ASoC: soc-pcm: fix the return value in dpcm_apply_symmetry()
[ Upstream commit 12ffd726824a2f52486f72338b6fd3244b512959 ]
In case, where the loops are not executed for a reason, the uninitialized
variable 'err' is returned to the caller. Make code fully predictible
and assign zero in the declaration.
