Daniel P. Berrangé cd1f25a9d4 tools: fix double error reporting in virt-login-shell
The public API entry points will call virDispatchError which
will print to stderr by default. We then jump to a cleanup
path which calls virDispatchError again.

We tried to stop the entry points printing to stderr, but
incorrectly called virSetErrorFunc. It needs a real function
that is a no-op, not a NULL function.

Once we fix virSetErrorFunc, then we need to use fprintf in
the cleanup path instead of virDispatchError.
