x86-64, NUMA: Make dummy node initialization path similar to non-dummy ones
Dummy node initialization in initmem_init() didn't initialize apicid
to node mapping and set cpu to node mapping directly by caling
numa_set_node(), which is different from non-dummy init paths.
Update it such that they behave similarly. Initialize apicid to node
mapping and call numa_init_array(). The actual cpu to node mapping is
handled by init_cpu_to_node() later.
