linux-aio: add `dev_max_batch` parameter to laio_co_submit()
This new parameter can be used by block devices to limit the
Linux AIO batch size more than the limit set by the AIO context.
file-posix backend supports this, passing its `aio-max-batch` option
previously added.
Add an helper function to calculate the maximum batch size.
