ANDROID: fix up abi issue with struct snd_pcm_runtime

A portion of the fix for CVE-2022-1048, commit 9cb6c40a ("ALSA: pcm:
Fix races among concurrent hw_params and hw_free calls") and
40f4cffb ("ALSA: pcm: Fix potential AB/BA lock with buffer_mutex and
mmap_lock"), 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
size:
