[ Upstream commit c92c74131a84b508aa8f079a25d7bbe10748449e ]

The blamed commit modified the driver to accept the addition of VID 0
without doing anything, but deleting that VID still fails:

[   32.080780] mv88e6085 d0032004.mdio-mii:10 lan8: failed to kill vid 0081/0

Modify mv88e6xxx_port_vlan_leave() to do the same thing as the addition.

Fixes: b8b79c414eca ("net: dsa: mv88e6xxx: Fix adding vlan 0")
