Subject: [PATCH] dbus: clear guid_from_server if send_negotiate_unix_fd failed
Once send_negotiate_unix_fd failed, this failure will happen, since
auth->guid_from_server has been set to some value before
send_negotiate_unix_fd. send_negotiate_unix_fd failure will lead to this
auth be handled by process_ok again, but this auth->guid_from_server is
not zero.
So we should clear auth->guid_from_server if send_negotiate_unix_fd
failed.
