When we are over our outbound limit ThreadSocketHandler would try to keep the connection if the peer was addnoded.
This didn't actually work for two reasons: It didn't actually run the accept code due to mistaken code flow, and because we have a limited number of outbound semaphores it couldn't actually use the connection.
Instead it leaked the socket, which might have caused issue #4034.
This patch just takes out the non-functioning white-listing for now.
