Nathan Huckleberry 73ea735073 net: sparx5: Fix return type of sparx5_port_xmit_impl ...

The ndo_start_xmit field in net_device_ops is expected to be of type
netdev_tx_t (*ndo_start_xmit)(struct sk_buff *skb, struct net_device *dev).

The mismatched return type breaks forward edge kCFI since the underlying
function definition does not match the function hook definition.

The return type of sparx5_port_xmit_impl should be changed from int to
netdev_tx_t.
