    net/mlx5: fix MTU initialization in device spawn
    
    Currently with mlx5 PMD, rte_eth_dev_get_mtu() doesn't return
    the MTU the device was set with, but the default one.
    It happens because mlx5_dev_spawn() is not setting the eth_dev->data->mtu
    field after getting the actual MTU from the driver,
    so the default value is kept.
    This patch fixes the issue by retrieving setting the value of priv->mtu
    to eth_dev->data->mtu.
