net: dsa: b53: do not program vlans when vlan filtering is off

Documentation/networking/switchdev.rst says:

- with VLAN filtering turned off: the bridge is strictly VLAN unaware and its
  data path will process all Ethernet frames as if they are VLAN-untagged.
  The bridge VLAN database can still be modified, but the modifications should
  have no effect while VLAN filtering is turned off.

This breaks if we immediately apply the VLAN configuration, so skip
writing it when vlan_filtering is off.
