[issue42140] asyncio.wait function creates futures set two times

[Diogo Dutra]

New submission from Diogo Dutra <diogodutradamata at gmail.com>:

The python3.9 code creates the futures set two times.
We can create this set before, avoiding the second creation.

This python3.9 behaviour breaks the aiokafka library, because it gives an iterator to that function, so the second iteration become empty.
