bonding: fix device name allocation error
The code to select names for the bonding interfaces was, for the
non-sysfs creation case, always using a hard-coded set of bond0, bond1,
etc, up to max_bonds. This caused conflicts for the second or
subsequent loads of the module.
Changed the code to obtain device names from dev_alloc_name().
