* case the guest acknowledges the interrupt to the device in
* its threaded irq handler, i.e. after the EOI but before
* unmasking, so at the time of unmasking the IRQ line is
* already down but our pending irr bit is still set. In such
* cases, injecting this pending interrupt to the guest is
* buggy: the guest will receive an extra unwanted interrupt.
*
* So we need to check here if the IRQ is actually still pending.
* As we are generally not able to probe the IRQ line status
* directly, we do it through irqfd resampler. Namely, we clear
* the pending status and notify the resampler that this interrupt
* is done, without actually injecting it into the guest. If the
* IRQ line is actually already deasserted, we are done. If it is
* still asserted, a new interrupt will be shortly triggered
* through irqfd and injected into the guest.
*
* If, however, it's not possible to resample (no irqfd resampler
* registered for this irq), then unconditionally inject this
* pending interrupt into the guest, so the guest will not miss
* an interrupt, although may get an extra unwanted interrupt.
