x86: Move llc_shared_map out of cpu_info
cpu_info is already with per_cpu, We can take llc_shared_map out
of cpu_info, and declare it as per_cpu variable directly.
So later referencing could be simple and directly instead of
diving to find cpu_info at first.
Also could make smp_store_cpu_info() much simple to avoid to do
save and restore trick.
