When configuring a bonded network interface, we by mistake configured
the slaves to have "bond0" as their master instead of the actual master
interface that was being configured.  We obviously never tested this
with a bonding interface named anything other than "bond0"...  The
correct thing to do is of course setting MASTER to $name, so do that.

This was originally commit ca9facdcdb88 in nsc-puppet-utils.
