net/mlx4_en: Count HW buffer overrun only once
[ Upstream commit 281e8b2fdf8e4ef366b899453cae50e09b577ada ]
RdropOvflw counts overrun of HW buffer, therefore should
be used for rx_fifo_errors only.
Currently RdropOvflw counter is mistakenly also set into
rx_missed_errors and rx_over_errors too, which makes the
device total dropped packets accounting to show wrong results.
Fix that. Use it for rx_fifo_errors only.
