Yinghai Lu 3b28cf32cc x86, numa: Fix numa_emulation code with memory-less node0 
This crash happens on a system that does not have RAM on node0.

When numa_emulation is compiled in, and:

 1. we boot the system without numa=fake...
 2. or we boot the system with numa=fake=128 to make emulation fail

we will get:

[    0.076025] ------------[ cut here ]------------
[    0.080004] kernel BUG at arch/x86/mm/numa_64.c:788!
[    0.080004] invalid opcode: 0000 [#1] SMP
[...]

need to use early_cpu_to_node() directly, because cpu_to_apicid
and apicid_to_node will return node0 that is not onlined.
