I do not think this will work (it never did). Bridge reinjects skb, does
not do another loop. Therefore when skb->dev == br0 and vlan_on_bond
hook is called, orig_dev == br0 as well. + No IFF_BONDING is set.

I have some kind nice solution in mind and I'm going to submit that as
a patch later (too many patches are in the wind atm).
