Before we allow port netdevs to be enslaved to a VRF master we need to
make sure the device's routing tables won't be flushed upon the
insertion of a l3mdev rule.

Note that we assume the notified l3mdev rule is a simple rule as used by
the VRF master. We don't check for the presence of other selectors such
as 'iif' and 'oif'.
