ASoC: soc-component: tidyup snd_soc_pcm_component_sync_stop()
commit 1e5ddb6ba7 ("ASoC: component: Add sync_stop PCM ops")
added snd_soc_pcm_component_sync_stop(), but it is checking
ioctrl instead of sync_stop. This is bug.
This patch fixup it.

Fixes: commit 1e5ddb6ba7 ("ASoC: component: Add sync_stop PCM ops")
