Use generic handlers to queue fsync() when AIO DIO is completed for O_SYNC file. Although we use our own bio->end_io function, we call dio_end_io() from it and thus, because we don't set any specific dio->end_io function, generic code ends up calling generic_dio_end_io() which is all what we need for proper O_SYNC AIO DIO handling.
