[PULL 1/6] iothread: Remove unused Error** argument in aio_context_set_aio_params

[Stefan Hajnoczi <stefanha@xxxxxxxxxx>]

From: Philippe Mathieu-Daudé <philmd@xxxxxxxxxx>

aio_context_set_aio_params() doesn't use its undocumented
Error** argument. Remove it to simplify.

Note this removes a use of "unchecked Error**" in
iothread_set_aio_context_params().
