When an RPC message is received with RPCSEC_GSS with an unknown service
(not RPC_GSS_SVC_NONE, RPC_GSS_SVC_INTEGRITY, or RPC_GSS_SVC_PRIVACY),
svcauth_gss_accept() returns AUTH_BADCRED, but svcauth_gss_release()
subsequently drops the response entirely, discarding the error.
Fix that so the AUTH_BADCRED error is returned to the client.
