openvswitch: properly refcount vport-vxlan module
After 614732eaa12d, no refcount is maintained for the vport-vxlan module. This allows the userspace to remove such module while vport-vxlan devices still exist, which leads to later oops. v1 -> v2: - move vport 'owner' initialization in ovs_vport_ops_register() and make such function a macro Fixes: 614732eaa12d ("openvswitch: Use regular VXLAN net_device device") Signed-off-by: Paolo Abeni <pabeni@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>
