ASoC: soc-pcm: don't use bit-OR'ed error

Current soc-pcm is using bit-OR'ed error

	ret |= snd_soc_component_close(component, substream);
	ret |= snd_soc_component_hw_free(component, substream);

The driver may return arbitrary error codes so they can conflict.
The bit-OR'ed error works only if the return code is always consistent.
This patch fixup it, and use *last* ret value.
