x86: x2apic, IR: Move eoi_ioapic_irq() into a CONFIG_INTR_REMAP section 



Address the following complier warning:

   arch/x86/kernel/apic/io_apic.c:2543: warning: `eoi_ioapic_irq' defined but not used

By moving that function (and eoi_ioapic_irq()) into an existing
#ifdef CONFIG_INTR_REMAP section of the code.

[ Impact: cleanup ]
