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. Signed-off-by: Ben Hutchings <ben@decadent.org.uk> Signed-off-by: David S. Miller <davem@davemloft.net>
