unix.7: EXAMPLES: server.c: End connection with END

Client wants to send END while server already closed the connection on
DOWN, so connection is broken instead of the Result = 0 in the sample on
sending a single DOWN.
Now, the server disconnects only on first END. After DOWN, all further
processing of number stops.
Patch does not handle cases of double END sending, multiple clients etc.
