python/qmp: remove Server.wait_closed() call for Python 3.12
This patch is a backport from
e03a3334b6
According to Guido in https://github.com/python/cpython/issues/104344 ,
this call was never meant to wait for the server to shut down - that is
handled synchronously - but instead, this waits for all connections to
close. Or, it would have, if it wasn't broken since it was introduced.
3.12 fixes the bug, which now causes a hang in our code. The fix is just
to remove the wait.
