x86/ioapic: Print the IRTE's index field correctly when enabling INTR

Browse Source 
When enabling interrupt remap, IOAPIC's RTE contains the interrupt_index
field of IRTE. This field is composed of the ->index and the ->index2 members
of 'struct IR_IO_APIC_route_entry' - but what we print out currently only
uses ->index.

Fix it.
