The entries[] array needs to be cacheline aligned to avoid false
sharing between different queues, each queue has a set of entries
in it that it writes to.

While it is aligned in practice today given that each array entry
before it is aligned, it's still clearer to explicitly require it
to be aligned, so add the annotation for that.
