[ Upstream commit 45ebf73ebcec88a34a778f5feaa0b82b1c76069e ]
Make sure SCTP_ADDR_{MADE_PRIM,ADDED} are sent only for associations that have been established.
These events are described in rfc6458#section-6.1 SCTP_PEER_ADDR_CHANGE: This tag indicates that an address that is part of an existing association has experienced a change of state (e.g., a failure or return to service of the reachability of an endpoint via a specific transport address).
