bonding: process the err returned by dev_set_allmulti properly in bond_enslave

Browse source

commit 9f5a90c107 upstream.

When dev_set_promiscuity(1) succeeds but dev_set_allmulti(1) fails,
dev_set_promiscuity(-1) should be done before going to the err path.
Otherwise, dev->promiscuity will leak.
