net: hns3: fix for skb leak when doing selftest

Browse source

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.
