In the next patch, we would like to couple into the engine wakeref to free the batch pool on idling. The caveat here is that we therefore want to track the engine wakeref more precisely and to hold it instead of the broader GT wakeref as we process the ioctl. v2: Avoid introducing odd semantics for a shortlived timeline->mutex acquisition interface.
