x86/smpboot: moves x86_topology to static initialize and truncate

Browse source

The #ifdeffery and the initializers in build_sched_topology() are just

Statically initialize the domain levels in the topology array and let
build_sched_topology() invalidate the package domain level when NUMA in
package is available.
