ASoC: Intel: Skylake: fix possible memory leak in skl_codec_device_init()
If snd_hdac_device_register() fails, 'codec' and name allocated in
dev_set_name() called in snd_hdac_device_init() are leaked. Fix this
by calling put_device(), so they can be freed in snd_hda_codec_dev_release()
and kobject_cleanup().
