[PATCH V2 net 4/4] net: ena: return error code from ena_xdp_xmit_buff

[Shay Agroskin]

The function mistakenly returns NETDEV_TX_OK regardless of the
transmission success. This patch fixes this behavior by returning the
error code from the function.

Fixes: 548c4940b9f1 ("net: ena: Implement XDP_TX action")
