For system with X86_FEATURE_TOPOEXT, current logic use APIC ID to
calculate shared_cpu_map. However, since APIC IDs are not guaranteed
to be contiguous for cores across different L3 (e.g. family17h system
w/ downcore configuration). This breaks the logic, and results in
incorrect L3 shared_cpu_map.
