net: don't try to ops lock uninitialized devs
We need to be careful when operating on dev while in rtnl_create_link().
Some devices (vxlan) initialize netdev_ops in ->newlink, so later on.
Avoid using netdev_lock_ops(), the device isn't registered so we
cannot legally call its ops or generate any notifications for it.
netdev_ops_assert_locked_or_invisible() is safe to use, it checks
registration status first.
