net/bonding: ensure slave interfaces are down before adding.

Browse Source 
The old ifenslave binary forcibly set new slave interface to down before
adding into the kernel, as a way of show it's version to the kernel. We
need to duplicate this so that the kernel doesn't think it's an old
ifenslave version using the bonding setup interface.
