[PATCH V2 net-next 10/11] net: hns3: add feature check when feature changed

[Peng Li]

From: Jian Shen <shenjian15@xxxxxxxxxx>

Local variable "changed" was defined to indicates features changed,
but was used only for feature NETIF_F_HW_VLAN_CTAG_RX. Add checking
for other features.

Fixes: 052ece6dc19c ("net: hns3: add ethtool related offload command")
