net/mlx4_en: get rid of ret_stats
mlx4 uses a private struct net_device_stats in a vain attempt
to avoid races.
This is buggy because multiple cpus could call mlx4_en_get_stats()
at the same time, so ret_stats can not guarantee stable results.
To fix this, we need to switch to ndo_get_stats64() as this
method provides per-thread storage.
This allows to reduce mlx4_en_priv bloat.
