ASoC: fix config error path
initialize ret to invalid value so that when we reach the config error path in soc_pcm_open, it will return the correct error code. without this patch, though config error path is executed, soc_pcm_open will return 0 in snd_pcm_open_substream and then cause double release of substream.
