When a host changes its IP address, the driver previously updated the host endpoint to the new IP before calling on_down. This caused on_down to mistakenly target the new IP for connection cleanup. This change reorders the operations to ensure on_down cleans up the old IP's resources before the host object is updated and on_up is called for the new IP.
