tipc: Eliminate configuration for maximum number of cluster nodes

Gets rid of the need for users to specify the maximum number of
cluster nodes supported by TIPC. TIPC now automatically provides
support for all 4K nodes allowed by its addressing scheme.

Note: This change sets TIPC's memory usage to the amount used by
a maximum size node table with 4K entries.  An upcoming patch that
converts the node table from a linear array to a hash table will
compact the node table to a more efficient design, but for clarity
it is nice to have all the Kconfig infrastruture go away separately.
