station: only add diagnostic interface when connected

Browse Source 
The diagnostic interface returns an error anyways if station is
not connected so it makes more sense to only bring the interface
up when its actually usable. This also removes the interface
when station disconnects, which was never done before (the
interface stayed up indefinitely due to a forgotten remove call).
