batman-adv: Set the txqueuelen to zero when creating soft interface
Like other virtual interfaces, e.g. br0, we don't need a transmit queue. Packets should only be queued on real interfaces which are underneath. In practice this patch makes little difference since the virtual interfaces can accept packets as fast as they come, but the patch will avoid bufferbloat questions to the mailling lists in the future.
