We mark edge-triggered interrupts with the HW bit set as queued to prevent the VGIC code from injecting LRs with both the Active and Pending bits set at the same time while also setting the HW bit, because the hardware does not support this. However, this means that we must also clear the queued flag when we sync back a LR where the state on the physical distributor went from active to inactive because the guest deactivated the interrupt. At this point we must also check if the interrupt is pending on the distributor, and tell the VGIC to queue it again if it is. Since these actions on the sync path are extremely close to those for level-triggered interrupts, rename process_level_irq to process_queued_irq, allowing it to cater for both cases.
