batman-adv: Place kref_get for bla_claim near use

It is hard to understand why the refcnt is increased when it isn't done near the actual place the new reference is used. So using kref_get right before the place which requires the reference and in the same function helps to avoid accidental problems causedy incorrect reference counting.
