Building a kernel without said option results in:
WARN: resolve_btfids: unresolved symbol bpf_session_cookie
This is a bare-minimum patch to sort it out.
There are other uses of the bpf_session_cookie thing spread out
thorought the file, they don't seem to break anything though.

I don't care how this gets addressed, I just want the warning gone.
So I am not going to fight any ideas how to do it, as long as it gets
done.
