x86-64, NUMA: Build and use direct emulated nid -> phys nid mapping

NUMA emulation copied physical NUMA configuration into physnodes[] and
used it to reverse-map emulated nodes to physical nodes, which is
unnecessarily convoluted.  Build emu_nid_to_phys[] array to map
emulated nids directly to the matching physical nids and use it in
numa_add_cpu().

physnodes[] will be removed with further patches.

- v2: Build failure when CONFIG_DEBUG_PER_CPU_MAPS due to missing
  local variable definition fixed.  Reported by Ingo.
