Align with qemu-kvm and prepare for IO exit fix: There is no need to run kvm_arch_process_irqchip_events in the inner VCPU loop. Any state change this service processes will first cause an exit from kvm_cpu_exec anyway. And we will have to reenter the kernel on IO exits unconditionally, something that the current logic prevents.
