intel-virtual-output: Flush the damage received message back to the local display 

After processing the Damage notification, we need to send a message back
to the Xserver to clear the pending damage before we will be sent more
events. To make sure that message is sent we need to flush the output,
as we may never flush the output queue otherwise.
