tipc: Cosmetic cleanup of topology service code

This patch contains a set of cosmetic changes to TIPC's network
topology service subsystem, including:

- updates to comments (including copyright dates)
- re-ordering structure fields to group them more logically
- removal of optional debugging code that is no longer required
- minor changes to whitespace to conform to Linux coding conventions
