x86: io-apic - code style cleaning for setup_IO_APIC_irqs

By changing printout form we are able to shrink (and clean up) code a bit.

Former printout example:

	init IO_APIC IRQs
	 IO-APIC (apicid-pin) 1-1, 1-2, 1-3 not connected.
	 IO-APIC (apicid-pin) 2-1, 2-2, 2-3 not connected.

New printout example:

	init IO_APIC IRQs
	 1-1 1-2 1-3 (apicid-pin) not connected
	 2-1 2-2 2-3 (apicid-pin) not connected
