Instead of removing this it should probably just return 0 and move it
down a few lines after setting or clearing the bit. Otherwise you will
strip the default VLAN on removal and I am pretty sure that will disable
all receives until the interface is reset and restores VLAN 0 from the
VF which maps to the default VLAN.
