Fix tradfri asyncio.wait

[cdce8p]

Proposed change

Releated to #99726

Starting with Python 3.11.0 asyncio.wait raises a TypeError if a coroutine is passed directly to asyncio.wait.
https://github.com/python/cpython/blob/v3.11.0/Lib/asyncio/tasks.py#L414-L415

At first it was slightly surprising to me that this wasn't caught be our test suite. However, looking the coverage for tradfri/config_flow.py is only ~80%. It wasn't really changed since the initial commit years ago #16665.

Looking at the code section in question, I wonder if it's even necessary / should be there. There are also no open issues for this particular bug.
