x86: call early_cpu_init at the same point

Call early_cpu_init() at the same (early) point in setup_arch(). The x86_64 code was calling it relatively late, after when other arch code need to do cpu-related setup which depends on it.

applied to tip/x86/urgent, thanks Jeremy.

Thanks. Curious to see if this causes any breakage, especially in numa-ish type systems.

no badness so far.
