drm/xe/drm_ras: Add per node cleanup action

cleanup_node_param() is not registered for previous node in case of counter
allocation failure, which results in stale memory of previous node that
isn't cleaned up on unwind. Add per node cleanup action which guarantees
cleanup on unwind and also simplifies the cleanup logic.
