net: hns3: store rx VLAN tag offload state for VF

The VF driver missed to store the rx VLAN tag strip state when
user change the rx VLAN tag offload state. And it will default
to enable the rx vlan tag strip when re-init VF device after
reset. So if user disable rx VLAN tag offload, and trig reset,
then the HW will still strip the VLAN tag from packet nad fill
into RX BD, but the VF driver will ignore it for rx VLAN tag
offload disabled. It may cause the rx VLAN tag dropped.
