net/mlx5e: Fix VF representors reporting zero counters to "ip -s" command
Although vf_vport entry of struct mlx5e_stats is never updated, its
values are mistakenly copied to the caller structure in the VF
representor .ndo_get_stat_64 callback mlx5e_rep_get_stats(). Remove
redundant entry and use the updated one, rep_stats, instead.
Fixes: 64b68e369649 ("net/mlx5: Refactor and expand rep vport stat group")
