For OpenStack Queens and later instances are setup with vhostuser
ports in server mode, with the OVS side of the port connecting
as a client to the vhostuser socket on disk; as a result we no
longer need to pass permissions information via dpdk-extra (the
two passed options are not valid in later OVS versions).
In addition, we should also whitelist the devices we're going to
use; this ensures that EAL initialization does not take an extended
period of time reducing the amount of time taken to restart OVS.
