We should check the attempt to downgrade forwarding modes -- if the VLAN has mode: route then no device connected to that VLAN should have VLAN mode set to bridge or irb.

Fix: check the VLAN/interface fwd mode compatibility
901bc93 
Connecting a bridge/IRB interface to two segments of a routed VLAN
results in a shared IP prefix used on both segments.

This change checks for the forwarding mode mismatch and triggers an
error that can be disabled with a defaults setting (because someone
might want to use the shared IP prefix)

It turns out several routed VLAN transformation tests relied on
this behavior, so they got the VLAN default tweak.

Fixes #1461
