direct-io: fix AIO regression The direct-io.c rewrite to use the iov_iter infrastructure stopped updating the size field in struct dio_submit, and thus rendered the check for allowing asynchronous completions to always return false. Fix this by comparing it to the count of bytes in the iov_iter instead.
