qemu: Bypass sending VIR_DOMAIN_EVENT_RESUMED event when TD VM reboot

When TD VM reboot, qemu process is recreated by destroying old and
creating new one. When new qemu process starts, it sends a RESUME
event while libvirt domain isn't in run state yet. Then event
VIR_DOMAIN_EVENT_RESUMED is sent out and confuse control plane.

Check priv->pausedShutdown and bypass the event for TD VM, for
normal VM, domain is in run state and already bypassing it.
