Subject: [net-next 04/12] i40e: remove error msg when vf with port vlan tries to remove vlan 0

From: Aleksandr Loktionov <aleksandr.loktionov@...el.com>

VF's attempt to delete vlan 0 when a port vlan is configured is harmless
in this case pf driver just does nothing.  If vf will try to remove
other vlans when a port vlan is configured it will still produce error
as before.
