network: ensure we pass tasks to asyncio.wait

In Python < 3.11, when passing a coroutine to asyncio.wait, it would
automatically be scheduled as a task. This isn't the case anymore with
Python 3.11. Now passing coroutines to asyncio.wait fails with:

 TypeError: Passing coroutines is forbidden, use tasks explicitly.

Let's ensure we schedule the coroutines as tasks before passing them on
to asyncio.wait.
