ipcpd: Send link state message before lsdb update0.12.3

When a new link is added, the link state update will be sent before
the database update, so the network is a little bit more quickly
aware. This improves odds of the DHT successfully enrolling at its
first attempt, reducing bootstrap time of a network.
