batman-adv: don't free resource when DAT is disabled
Freeing all the resources when DAT is disabled need a much more complicated locking system to prevent concurrent enable/disable operations to destroy the internal state of the component. For now it is safe to avoid such freeing operation when DAT is disabled.
