Subject: [net 01/10] net/mlx5: Remove NULL check before dev_{put, hold}

From: Yang Li <[email-masked]>

The call netdev_{put, hold} of dev_{put, hold} will check NULL,
so there is no need to check before using dev_{put, hold},
remove it to silence the warning：

./drivers/net/ethernet/mellanox/mlx5/core/en/rep/tc.c:714:2-9: WARNING: NULL check before dev_{put, hold} functions is not needed.
