    Don't fail when trying to unbind a router

    If a router is already unbound from an l3 agent, don't fail. Log
    the condition and go on. This is harmless since it can happen
    due to a delete race condition between multiple neutron-server
    processes. One delete request can determine that it needs to
    unbind the router. A second process may also determine that it
    needs to unbind the router. The exception thrown will result
    in a port delete failure and cause nova to mark a deleted instance
    as ERROR.
