[MINOR] do not create a socket if there is no server

Since the distinction of backends and frontends, it has become
possible that some requests reach a frontend which has no
backend parameters. We must not create a socket on the backend
side just to destroy it later in such a case. The real problem
comes from the dispatch mode not being explictly stated.
