[PATCH 04/10] ASoC: rsnd: indicate unknown error at rsnd_dai_call()

[Kuninori Morimoto]

From: Kuninori Morimoto <kuninori.morimoto.gx at renesas.com>

Current rsnd_dai_call() doesn't indicate error message,
thus it is very difficult to know the issue
when strange things happen.
This patch indicates error for it.
