H A Dio_uring.c9d54bd6a Thu Sep 08 10:56:54 CDT 2022 Pavel Begunkov <asml.silence@gmail.com> io_uring/iopoll: fix unexpected returns

We may propagate a positive return value of io_run_task_work() out of
io_iopoll_check(), which breaks our tests. io_run_task_work() doesn't
return anything useful for us, ignore the return value.
