tipc: Remove obsolete comments about routing table updates

Eliminates a block of comments that describe how routing table updates
are to be handled. These comments no longer apply following the removal
of TIPC's prototype multi-cluster support.

Note that these changes are essentially cosmetic in nature, and have
no impact on the actual operation of TIPC.

- * Routing table management - five cases to handle:
- *
- * 1: A link towards a zone/cluster external node comes up.
- *    => Send a multicast message updating routing tables of all
- *    system nodes within own cluster that the new destination
- *    can be reached via this node.
- *    (node.establishedContact()=>cluster.multicastNewRoute())
- *
- * 2: A link towards a slave node comes up.
- *    => Send a multicast message updating routing tables of all
- *    system nodes within own cluster that the new destination
- *    can be reached via this node.
- *    (node.establishedContact()=>cluster.multicastNewRoute())
- *    => Send a  message to the slave node about existence
- *    of all system nodes within cluster:
- *    (node.establishedContact()=>cluster.sendLocalRoutes())
- *
- * 3: A new cluster local system node becomes available.
- *    => Send message(s) to this particular node containing
- *    information about all cluster external and slave
- *     nodes which can be reached via this node.
- *    (node.establishedContact()==>network.sendExternalRoutes())
- *    (node.establishedContact()==>network.sendSlaveRoutes())
- *    => Send messages to all directly connected slave nodes
- *    containing information about the existence of the new node
- *    (node.establishedContact()=>cluster.multicastNewRoute())
- *
- * 4: The link towards a zone/cluster external node or slave
- *    node goes down.
- *    => Send a multcast message updating routing tables of all
- *    nodes within cluster that the new destination can not any
- *    longer be reached via this node.
- *    (node.lostAllLinks()=>cluster.bcastLostRoute())
- *
- * 5: A cluster local system node becomes unavailable.
- *    => Remove all references to this node from the local
- *    routing tables. Note: This is a completely node
- *    local operation.
- *    (node.lostAllLinks()=>network.removeAsRouter())
- *    => Send messages to all directly connected slave nodes
- *    containing information about loss of the node
- *    (node.establishedContact()=>cluster.multicastLostRoute())
- *
