[LTP] [PATCH v3 1/3] aio_tio: fix error diagnosis for byte transfers

[Matthias Maennich]

In case the expected bytes written during an async io operation did not
match the actually written ones, the wrong error code (res2) had been
reported. Correct that to reflect the error condition (res!=bytes).
