[net-next 07/15] net/mlx5: DR, Adjust structure member to reduce memory hole

[Saeed Mahameed <saeed@kernel.org>]

From: Rongwei Liu <rongweil@nvidia.com>

Accord to profiling, mlx5dr_ste/mlx5dr_icm_chunk are the two
hot structures. Their memory layout can be optimized by
adjusting member sequences.

Struct mlx5dr_ste size changes from 64 bytes to 56 bytes.

In the upcoming commits, struct mlx5dr_icm_chunk memory layout
will change automatically after removing some members.
Keep it untouched here.
