When an interrupt is rerouted to a different I/O APIC pin the relevant
entry of the irq_2_pin list should get updated accordingly so that
operations are performed on the correct redirection entry.
This is already done by the 32-bit variation of the code and here is a
complementing 64-bit implementation. Should make someone's decision less
tough when merging the two. ;)
