Comment (by asn):
Agreed on only doing cleanup in `cleanup_intro_points()`.
Not sure about the `circuit_retries` counter situation. A real hibernation
callback is probably not easy to do in a cross-platform way, and resetting
the retries count is a recipe for guard discovery attacks. However, IIUC
this bug is not as impotant as the cleanup issue.
