In such case, sound driver should be stopped even though it was playbacking/capturing. Otherwise clock open/close counter mismatch happen. One headache was that we can't skip unbind in error case because unbind operation doesn't check return value from each drivers. snd_soc_disconnect_sync() was added for these purpose, and Renesas sound card only is used it. But now, ALSA SoC automatically disconnect sound card when sound driver was unbinded. Thus, snd_soc_disconnect_sync() is no longer needed. This patch removes it.
