net: hns3: fix error VF index when setting VLAN offload

In original codes, the VF index used incorrectly in function
hclge_set_vlan_rx_offload_cfg() and hclge_set_vlan_rx_offload_cfg().
When VF id is greater than 8, for example 9, it will set the
same bit with VF id 1.

This patch fixes it by using  vport->vport_id % HCLGE_VF_NUM_PER_CMD /
HCLGE_VF_NUM_PER_BYTE as the array index, instead of vport->vport_id /
HCLGE_VF_NUM_PER_CMD.
