Subject: net: hns3: don't allow user to change vlan filter state
Patch-mainline: v5.1-rc1
Git-commit: 77af09c6780b1394a1e888a6862d49cadc0247fa
References: bsc#1126390

When user disables vlan filter, and adds vlan device, it won't
notify the driver the update the vlan filter. In this case, when
user enables vlan filter again, the packets with new vlan tag
will be filtered by vlan filter.
