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")
