BUG/MEDIUM: mux-h2: fix crash when checking for reverse connection after error

If the connection is closed in h2_release(), which is indicated by ret<0, we
must not dereference conn anymore. This was introduced in 2.9-dev4 by commit
5053e8914 ("MEDIUM: h2: prevent stream opening before connection reverse
completed") and detected after a few hours of runtime thanks to running with
pool integrity checks and caller enabled. No backport is needed.
