ASoC: soc-pcm: check DAI activity under soc_pcm_apply_symmetry()

Browse source

soc_pcm_apply_symmetry() is used like below in all cases.

	if (snd_soc_dai_active(dai)) {
		err = soc_pcm_apply_symmetry(fe_substream, dai);
		...
	}

Because of this style, the code is deep nested.
This patch checks it under soc_pcm_apply_symmetry(), and makes code simple.

	static int soc_pcm_apply_symmetry(...)
	{
		...
=>		if (!snd_soc_dai_active(...))
			return 0;
		...
	}

=>	ret = soc_pcm_apply_symmetry();
	if (ret < 0)
		...
