[PATCH 6.1 199/280] net/mlx5e: Account for netdev stats in ndo_get_stats64

[ Upstream commit 476681f10cc1e0e56e26856684e75d4678b072b2 ]

The driver's ndo_get_stats64 callback is only reporting mlx5 counters,
without accounting for the netdev stats, causing errors from the network
stack to be invisible in statistics.

Add netdev_stats_to_stats64() call to first populate the counters, then
add mlx5 counters on top, ensuring both are accounted for (where
appropriate).
