Subject: net: hns3: remove unnecessary frag list checking in
 hns3_nic_net_xmit()
Patch-mainline: v5.8-rc1
Git-commit: 5c6cfd309faa7a1958c14b937ba9b95abb1427de
References: jsc#SLE-14777

The skb_has_frag_list() in hns3_nic_net_xmit() is redundant, since
skb_walk_frags() includes this checking implicitly.
