net: hns3: Fix error of checking used vlan id

Browse Source 
[ Upstream commit 54e97d117b ]

PF uses hdev->vlan_table to manage the port vlan table. In function
hclge_set_vlan_filter_hw(), it checks whether a vlan id has been used,
by foreach all the vport bits. It should use macro HCLGE_VPORT_NUM,
not VLAN_N_VID as the foreach condition.

Fixes: 6c251711b3 ("net: hns3: Disable vf vlan filter when vf vlan table is full")
