ipcpd: Fix shutdown of link-state routing

The link_state component tried to unregister from the notifier while
it had threads running.

The deadlock happens when notifier_event had a rdlock trying to delete
a neighbour, while notifier_unreg tries to take the write lock. And
the delete can't complete in the notifier.

We need to make sure that all threads are stopped before unregistering
from the notifier.

Updated link_state to use the start/stop() paradigm and not
create/cancel threads within init/fini().
