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

Current rsnd_dai_call returns immediately if rsnd_mod_call return fail.
Thus, each callback-count can be unbalanced for example .init was OK,
start was OK, but, .stop was not OK. This case .quit should be called
but isn't called. And, rsnd_dai_stream_quit() also not be called.
rsnd_dai_call() should call all .stop/.quit eventhough it returns error.
