There can be at most one consumer per volatile queue instance. This consumer must also have attached on the same channel/session as the creator of the queue. Prior to this commit, it was possible for clients on other connections or sessions to attach a receiving link to an existing volatile queue name, even though no messages would be delivered. It's better for RabbitMQ to directly refuse the link at attach time. (cherry picked from commit 0843704)
