ANDROID: fix up abi issue with struct snd_pcm_runtime, again

A portion of the fix for CVE-2022-1048, commit 9017201e ("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:
