x86/ioapic: Restore IO-APIC irq_chip retrigger callback
commit 020eb3daaba2857b32c4cf4c82f503d6a00a67de upstream.
commit d32932d02e18 removed the irq_retrigger callback from the IO-APIC
chip and did not add it to the new IO-APIC-IR irq chip.
Unfortunately the software resend fallback is not enabled on X86, so edge
interrupts which are received during the lazy disabled state of the
interrupt line are not retriggered and therefor lost.
Restore the callbacks.
