For hardware limitation, port VLAN filter is port level, and
effective for all the functions of the port. So if not support
port VLAN bypass, it's necessary to disable the port VLAN filter,
in order to support function level VLAN filter control.

Fixes: 2ba306627f59 ("net: hns3: add support for modify VLAN filter state")
