net: hns3: fix for skb leak when doing selftest
If hns3_nic_net_xmit does not return NETDEV_TX_BUSY when doing a loopback selftest, the skb is not freed in hns3_clean_tx_ring or hns3_nic_net_xmit, which causes skb not freed problem. This patch fixes it by freeing skb when hns3_nic_net_xmit does not return NETDEV_TX_OK.
