datapath: Renumber non-upstreamable interfaces.

Browse Source 
The interfaces related to tunneling aren't finalized enough to be
sent upstream but we also still want to retain them in the OVS
repository.  Since userspace should be compatible with both versions
of the kernel, this renumbers the tunnel interfaces to high numbers
so that we can continue to add new interfaces without conflict.
