[PATCH] aio: avoid extra aio_{read,write} call when ki_left == 0
Recently aio_p{read,write} changed to perform retries internally rather than returning -EIOCBRETRY. This inadvertantly resulted in always calling aio_{read,write} with ki_left at 0 which would in turn immediately return 0. Harmless, but we can avoid this call by checking in the caller.
