when acpi=off, cpu_to_apicid is ready after get_smp_config
so need to move init_cpu_to_node after it.

otherwise, we will get wrong cpu->node mapping, and it will rely on
amd_detect_cmp() to correct it - but that is too late as
setup_per_cpu_data is already called before that so  we will get
per_cpu_data on the wrong node.
