Hi Ričardas,

For tests like this you should set last error to some known value before
calling the function. And it would be better to split them up; one test
for the return value and one for the error.

> +    todo_wine ok(num_bytes == 0, "Number of bytes transfered is %u\n", num_bytes);

You may want to call GetQueuedCompletionStatus again here to show that
this was the last completion.
