[neutron] Properly create ovs bridges in mappings for DPDK

1. Create bridges with datapath_type=netdev parameter so that neutron
   ovs-agent wouldn't recreate it dropping all the custom settings
2. Delete --no-wait flag to make sure a bridge/port was in fact created
   by ovs-vswitchd in order to prevent further commands from failing
