i40evf: remove leftover VLAN filters 

If we're using VLANs and communications with the PF fail during
shutdown, we will leak memory because not all of the VLAN filters will
be removed. To eliminate this possibility, go through the list again
right before the module is removed and delete any leftover entries.
