x86/topology: Handle CPUID bogosity gracefully
Joseph reported that a XEN guest dies with a division by 0 in the package
topology setup code. This happens if cpu_info.x86_max_cores is zero.
Handle that case and emit a warning. This does not fix the underlying XEN bug,
but makes the code more robust.
