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.
