Hey Joe,
This looks good to me and fixes the root cause which is even better. I'm fairly new to OVS, so my ack likely doesn't mean much :)

It happens because refs to a netdev still exist (in this case, likely the tunnel has a ref to the netdev) when the main thread tries to delete the netdev. Thus, the netdev never gets deleted and the netdev cannot be recreated with a new type. I tested out the fix and it works with my patch as well.
