[PATCH] net/mlx5: fix internal SQ item definition

[PATCH] net/mlx5: fix internal SQ item definition

[Gregory Etelson]

When DPDK copies flow items with the `rte_flow_conv` call, it assumes
that size of PMD private data has pointer size - see patch [1]

MLX5 PMD defined `struct mlx5_rte_flow_item_sq` as 32 bits.
As the result, on 64 bits systems, when DPDK copied
MLX5_RTE_FLOW_ITEM_TYPE_SQ item, the target buffer was assigned
additional 32 bits.

The patch expands size of `struct mlx5_rte_flow_item_sq` to 64 bits
on 64 bits systems.
