This series fixes couple of issues with recent topology related code.
1. Maintain consistency while building the topology. Use the numa
   information passed from user to build the apic_id.
2. Fix uninitialized memory with -device and CPU hotplug

Here are the discussion thread.

v2:
 - Used the numa information from CpuInstanceProperties for building
   the apic_id suggested by Igor.
 - Also did some minor code re-aarangement to take care of changes.
 - Dropped the patch "Simplify CPUID_8000_001E" from v1. Will send
   it later.

v1:
