    os-vif: do not set Route.interface if None
    
    The Route.interface field in os-vif is currently
    non-nullable, which means it must be something other
    than None if set.
    
    There is no code in nova that sets the interface field
    on the nova.network.model.Route object, so it defaults
    to None and is always set to None on the os-vif Route
    object, which fails with:
    
    "ValueError: Fieldinterface' cannot be None"
    
    We don't hit this in the gate because we don't test with
    subnets that have host_routes set.

  I cannot see where the 'interface' is set on the Nova 'Route' object.
  The object only seems to be created in one place.
