Currently, the default VLAN (vlan id 0) will never be deleted from the
hardware VLAN table based on hns3 PF device. As a result, even a
non-zero PVID is set by calling rte_eth_dev_set_vlan_pvid based on hns3
PF device, packets with VLAN 0 and without VLAN are still received by PF
driver in Rx direction.
This patch deletes the restriction that VLAN 0 cannot be removed in PVID
configuration to ensure packets without PVID will be filtered when PVID
is set. And the patch adds VLAN 0 to the soft list when initializing
vlan configuration to ensure that VLAN 0 will be deleted from the
hardware VLAN table when device is closed.
