net/hns3: fix default VLAN filter configuration for PF

Currently, By default VLAN filter is enabled during initialization and
couldn't be turned off based on hns3 PF device. If upper applications
don't call rte_eth_dev_vlan_filter API function to set vlan based on
hns3 PF device, hns3 PF PMD driver will can't receive the packets with
vlan tag.  It will leads to some compatibility issues, the behaviors of
using hns3 network engine and other NICs are different.

This patch disables the VLAN filter during initialization and allows the
upper level applications to enable or disable the VLAN filter.
