[PATCH 2/2] ASoC: soc-core: use device_unregister() if rtd allocation failed

[Kuninori Morimoto]

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

Because soc_free_pcm_runtime(rtd) checks rtd pointer and freeing
rtd->xxx, it doesn't work correctly in case of rtd allocation failed.

We need to use device_unregister(dev) in such case.
This patch fixup it.
