net/mlx5: Don't store reserved part in FTEs and FGs
The current code stores fte_match_param in the software representation of FTEs and FGs. fte_match_param contains a large reserved area at the bottom of the struct. Since downstream patches are going to hash this part, we would like to avoid doing so on a reserved part.
