ovs: wait for the link to be ready before activating

Browse Source 
When activating an ovs-interface we already wait for the cloned MAC
address to be set, ifindex is present and platform link also present but
in some cases this is not enough.

If an udev rule is in place it might modify the interface when it is in
a later stage of the activation causing some race conditions or
problems. In order to solve that, we must wait until the link is fully
initialized.
