Close a race condition that causes cpr-transfer to lose VFIO interrupts on ARM. CPR stops VCPUs but does not disable VFIO interrupts, which may continue to arrive throughout the transition to new QEMU. CPR calls kvm_irqchip_remove_irqfd_notifier_gsi in old QEMU to force future interrupts to the producer eventfd, where they are preserved. Old QEMU then destroys the old KVM instance. However, interrupts may already be pending in KVM state. To preserve them, call ioctl KVM_DEV_ARM_VGIC_SAVE_PENDING_TABLES to flush them to guest RAM, where they will be picked up when the new KVM+VCPU instance is created.
