xen: mask extended topology info in cpuid
commit 82d6469916c6fcfa345636a49004c9d1753905d1 upstream.
A Xen guest never needs to know about extended topology, and knowing
would just confuse it.
This patch just zeros ebx in leaf 0xb which indicates no topology info,
preventing a crash under Xen on cpus which support this leaf.
