x86: fix 2.6.27rc1 cannot boot more than 8CPUs
Jeff Chua reported that booting a !bigsmp kernel on a 16-way box
hangs silently.
this is a long-standing issue, smp start AP cpu could check the
apic id >=8 etc before trying to start it.
achieve this by moving the def_to_bigsmp check later and skip the
apicid id > 8
[ mingo@elte.hu: clean up the message that is printed. ]
