[PATCH] Fix random crashes in http_cleanup()

For some reason, http_cleanup was running all active slots, which could lead in situations where a freed slot would be accessed in fill_active_slots. OTOH, we are cleaning up, which means the caller doesn't care about pending requests. Just forget about them instead or running them.

 I just think we don't care, so this fix should be okay.
