CASTOR-4751: tapeserverd does not report drive as empty and does not finish...

CASTOR-4751: tapeserverd does not report drive as empty and does not finish client session if user does not have migration access-rights

The error situation was already generating an exception, which went all the way to the caller
of the data transfer session. It is now intercepted and the client is notified synchronously.
The session now ends successfully (the drive was not touched).
