Add error reporting for unreleased PERSIST internal buffers in
iris_check_num_queued_internal_buffers(). This ensures all buffer types
are checked and logged if not freed during session close, helping to
detect memory leaks and improve driver robustness. No change to buffer
lifecycle or allocation logic.
