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.
