Don't rely on this for anything, it's just a test case / demo.

This is cleaner than having the app juggle an SQ and CQ ring,
just wrap them in struct io_uring and have the API always take
that. This means the app doesn't need to worry about the different
types of rings, and that we only need to pass in one argument
for setup/teardown.
