In the MLD case, the information from the transition management request is relevant during the association process in order to filter out links that were disallowed by the BTM request. Also, the information remains useful should a connection attempt fail. To enable these scenarios, keep the information around until the connection has completed. As this might make it impossible to establish a connection, also clear this information at the same time that a normal BSS ignore is cleared to avoid getting stuck in case the transition fails unexpectedly.
