Nate Johnston e459b20fb5 Do not delete trunk bridges if service port attached ... When a deployment has instance ports that are neutron trunk ports with DPDK vhu in vhostuserclient mode, when the instance reboots nova will delete the ovs port and then recreate when the host comes back from reboot. This quick transition change can trigger a race condition that causes the tbr trunk bridge to be deleted after the port has been recreated. See the bug for more details. This change mitigates the race condition by adding a check for active service ports within the trunk port deletion function.
