Link discovery bug fixes.

* Don't send link events if you're not master for the destination switch
* Also, inter-instance links are now discovered unidirectionally (one by
  each instance) rather than bidirectionally by one of the instances.
  The first fix coupled with the strange inter-instance link discovery
  semantics meant that one of the links was dropped.
