Dissectors don't need a journey of self discovery.
They already know who they are when they register themselves. Saving the handle then to avoid finding it later. Not sure if this will increase unnecessary register_dissector functions (instead of using create_dissector_handle in proto_reg_handoff function) when other dissectors copy/paste, but it should make startup time a few microseconds better.
