[libvirt] [PATCH] qemu: fix not end the job after use OpenGraphics(FD) and get fail when exit monitor
If guest unexpect exit(qemu process be killed) and get failed when exit the monitor, guest job still handled by old function, this will make guest cannot start later. Need call qemuDomainObjEndJob to release job status before unref vm.
