x86: clear IO_APIC before enabing apic error vector.
4 socket quad core, 8 socket quad core will do apic ID lifting for BSP.
But io-apic regs for ExtINT still use 0 as dest.
so when we enable apic error vector in BSP, we will get one APIC error.
CPU: L1 I Cache: 64K (64 bytes/line), D cache 64K (64 bytes/line)
CPU: L2 Cache: 512K (64 bytes/line)
CPU 0/4 -> Node 0
CPU: Physical Processor ID: 1
CPU: Processor Core ID: 0
SMP alternatives: switching to UP code
ACPI: Core revision 20070126
enabled ExtINT on CPU#0
ESR value after enabling vector: 00000000, after 0000000c
APIC error on CPU0: 0c(08)
ENABLING IO-APIC IRQs
Synchronizing Arb IDs.
So move enable_IO_APIC from setup_IO_APIC into setup_local_APIC and call it
before enabling the ACPI error vector.
