The OVS kernel module most likely comes with your kernel, so you
cannot completely remove it. To remove a device like this, you can use
ovs-dpctl to delete it then remove the OVS module:

# ovs-dpctl del-dp ovs-system
# rmmod openvswitch

(A reboot should have the same effect)

This looks like a piece of openstack that plugs on top of OVS.
