If we don't do this, we'll never trigger the backoff exponential timer
since it's impossible to distinguish between Initialization NAK's and
general errors.
Also:
* Implement some missing bits from RFC 5036;
* remove superfluous log message in session_shutdown()
(send_notification() logs that we're sending a fatal notification).
Regression introduced by commit 8819fc3.
Fixes the following ANVL LDP regressions: 6.19 and 6.21.
