Before this change, the function used to return 1 even if more
completions were reaped underneath.

Not a functional issue, as only place actual count mattered was in
io_uring, but it did not rely on this return anyway and used
completion-batching to process multiple completions.

But this was bit confusing, so good to have this cleaned up.
