Remove ovs from dpdk bridge config

This partially reverts commit f4d2d7ddce4297ffb65d78c151c2ab12c4443f74
OVS in config file leads to errors with dpdk bridge setup after
reboot and eventually to dpdk bridge absence.
Error is like: "ifup@br\x2dprv.service: Unit is bound to
inactive unit sys-subsystem-net-devices-br\x2dprv.device. Stopping, too."

The patch is also fixing success criteria for bridge creation to
avoid false positive when some ports have similar names.
