llc2: Fix silent failure of llc_station_init()
llc_station_init() creates and processes an event skb with no effect
other than to change the state from DOWN to UP. Allocation failure is
reported, but then ignored by its caller, llc2_init(). Remove this
possibility by simply initialising the state as UP.
