[PATCH] x86_64: fix cpu_to_node setup for sparse apic_ids

While booting with SMT disabled in bios, when using acpi srat to setup
cpu_to_node[], sparse apic_ids create problems.

Without this patch, intel x86_64 boxes with hyperthreading disabled in the
bios (and which rely on srat for numa setup) endup having incorrect values in
cpu_to_node[] arrays, causing sched domains to be built incorrectly etc.
