Hint from upstream. Sounds plausible that this might be the upstream fix:

I guess 4.3 started to be more aggressive there since I never saw this before 4.3 and there even on a non-NUMA system. But having a grant-table mapping taken away from the dom0 kernel without xenstored being involved would explain it tripping over that now bad pointer.
