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())
*
