[PATCH 1/4] ASoC: topology: Do not call snd_soc_remove_pcm_runtime() for ignored links

[Peter Ujfalusi <peter.ujfalusi@linux.intel.com>]

If a link has been ignored then it is not even added.
The snd_soc_get_pcm_runtime() will return NULL as the runtime will does
not exist.
We can just skip this step to avoid performing a lookup to do nothing.
