linux-aio: add `dev_max_batch` parameter to laio_io_unplug()
Between the submission of a request and the unplug, other devices
with larger limits may have been queued new requests without flushing
the batch.
Using the new `dev_max_batch` parameter, laio_io_unplug() can check
if the batch exceeds the device limit to flush the current batch.
