[PATCH 11/14] auth: fix use of uninitialized variable err

[Justus Winter]

Previously a plausible execution path existed so the value of err was
undefined at the end of the function, making the function return
arbitrary error values. Fix this by initializing it to 0.

Found using the Clang Static Analyzer.

* auth/auth.c (S_auth_server_authenticate): Initialize err to 0.
