bond: Use bond_enable_slave at slave registration.

Slave registration should go through the normal slave enabling
facilities instead of doing it by hand.  Before this patch, newly
created slaves would have no tag associated with them.
Furthermore, any further changes to how slaves are enabled would
not be picked up by the registration code.
