Stop messing with networks we did not create. [1/1]

We used to have code that added all private networks to our
fixed-to-floating router in an effort to ensure that newly-created
nodes could talk to the metadata service.  However, we now have
quantum-metadata-service working, so that code is worse than useless
-- it did not restrict itself to talking to netowrks that our recipes
had created.

Since we no longer need it, just cut it out.
