Currently, we can ask to authenticate DATA chunks and we can send DATA chunks on the same packet as COOKIE_ECHO, but if you try to combine both, the DATA chunk will be sent unauthenticated and peer won't accept it, leading to a communication failure. This happens because even though the data was queued after it was requested to authenticate DATA chunks, it was also queued before we could know that remote peer can handle authenticating, so sctp_auth_send_cid() returns false. The fix is whenever we set up an active key, re-check send queue for chunks that now should be authenticated. As a result, such packet will now contain COOKIE_ECHO + AUTH + DATA chunks, in that order.
