net: ethernet: litex: Fix return type of liteeth_start_xmit
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 liteeth_start_xmit should be changed from int to
netdev_tx_t.
