Avoid list allocation 

This is simmilar to https://github.com/rabbitmq/rabbitmq-server/pull/14056.
The performance benefit is probably negligbile though since this is
called only after each batch of Ra commands.
Nevertheless, it's unnecessary to allocate a list with 3 elements and
therefore 6 words on the heap, so let's optimise it.
