BUG/MAJOR: frontend: don't dereference a null conn on outgoing connections

Browse Source 
Recently merged commit 0cfe388 ("MINOR: frontend: retrieve the ALPN name when
available") assumed that the connection is always known in frontend_accept()
which is not true for outgoing peers connections for example.

No backport needed.
