x86: move init_cpu_to_node after get_smp_config
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.
