Suresh Siddha 345077cd98 x86: fix intel x86_64 llc_shared_map/cpu_llc_id anomolies
Impact: fix wrong cache sharing detection on platforms supporting > 8 bit apicid's

In the presence of extended topology eumeration leaf 0xb provided
by cpuid, 32bit extended initial_apicid in cpuinfo_x86 struct will be
updated by detect_extended_topology(). At this instance, we should also
reinit the apicid (which could also potentially be extended to 32bit).

With out this there will potentially be duplicate apicid's populated in the
per cpu's cpuinfo_x86 struct, resulting in wrong cache sharing topology etc
detected by init_intel_cacheinfo().
