batman-adv: Only use int up and down gw representation
It is not save to provide memory for an int and then cast the pointer to it to long*. It is better to standardize the up and down gateway bandwith representation to simple ints and only use long inside conversation routines. Signed-off-by: Sven Eckelmann <sven@narfation.org>
