[PATCH v2] net/mlx5e: Make use of mlx5_core_warn()

to replace printk(KERN_WARNING ...) with mlx5_core_warn() kindly
if we use mlx5_core_warn(), the prefix "mlx5:" not needed

in mlx5e it is netdev stack so netdev_warn(priv->netdev, "foo bar");
please.

Saeed,

That file is full of mlx5_core_* prints, even in the same function where
Cai is changing, you will find mlx5_core_warn().

Thanks

please.

$ git grep -E "mlx5_core_(warn|info|err)" 
drivers/net/ethernet/mellanox/mlx5/core/en_tc.c  | wc -l
4

$ git grep -E "netdev_(warn|info|err)" 
drivers/net/ethernet/mellanox/mlx5/core/en_tc.c  | wc -l
24

4 vs 24, a big win for netdev ;-)

4 is not full. Many of mlx5 files has some leftovers historical code,
doesn't mean we need to keep the old habits ..
