src: add nullptr check for session in DEBUG macro by danbev · Pull Request #18815 · nodejs/node

Currenlty when configuring --debug-http2
/test/parallel/test-http2-getpackedsettings.js will segment fault:

$ out/Debug/node test/parallel/test-http2-getpackedsettings.js
Segmentation fault: 11

This is happening because the settings is created with the Environment in
PackSettings:
Http2Session::Http2Settings settings(env);
This will cause the session to be set to nullptr. When the init
function is later called the expanded DEBUG_HTTP2SESSION macro will
cause the segment fault when the session is dereferenced.

I'm not sure about what the proper solution is here as I'm not very
familiar with the http2 code yet. Creating this so that others can
provide some feedback.
