[PATCH v9 05/10] net/mlx5: fix Rx split segment counter type

[Thomas Monjalon <thomas@monjalon.net>]

In the API, rx_nseg and max_nseg are uint16_t.
In mlx5, MLX5_MAX_RXQ_NSEG is 32.
So there is no reason to have rxseg_n as uint32_t.
Reduce the fields to uint16_t and move them to avoid struct holes.

Fixes: 9f209b59c8b0 ("net/mlx5: support Rx buffer split description")
Fixes: 572c9d4bda08 ("net/mlx5: fix shared Rx queue segment configuration match")
