commit a9b4f08770b415f30f2fb0f8329a370c8f554aa3 upstream.
commit d32932d02e removed the irq_retrigger callback from the IO-APIC
chip and did not add it to the new IO-APIC-IR irq chip.
There is no harm because the interrupts are resent in software when the
retrigger callback is NULL, but it's less efficient. So restore them.
