net: hns3: fix port vlan filter not disabled issue

[ Upstream commit f5db7a3b65c84d723ca5e2bb6e83115180ab6336 ]

According to hardware limitation, for device support modify
VLAN filter state but not support bypass port VLAN filter,
it should always disable the port VLAN filter. but the driver
enables port VLAN filter when initializing, if there is no
VLAN(except VLAN 0) id added, the driver will disable it
in service task. In most time, it works fine. But there is
a time window before the service task shceduled and net device
being registered. So if user adds VLAN at this time, the driver
will not update the VLAN filter state,  and the port VLAN filter
remains enabled.

To fix the problem, if support modify VLAN filter state but not
support bypass port VLAN filter, set the port vlan filter to "off".

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