x86: irq: fix apicinterrupts on 64 bits

Impact: Fix interrupt via the apicinterrupt macro

Checkin 939b7871

 changed the
"interrupt" macro, but the "interrupt" macro is also invoked
indirectly from the "apicinterrupt" macro.

The "apicinterrupt" macro probably should have its own collection of
systematic stubs for the same reason the main IRQ code does; as is it
is a huge amount of replicated code.
