A portion of the fix for CVE-2022-1048, commit 0f6947f5f5 ("ALSA: pcm:
Fix races among concurrent hw_params and hw_free calls"), caused an ABI
break by adding a new field to struct snd_pcm_runtime. Because we have
to keep this new addition, it is safe to move it to the end of the
structure because this is only ever created by the sound core, and
referenced as a pointer everywhere else.
This does require a .xml update also to handle the increased structure
