>Not sending response for opcodes that aren't supported in switchdev mode

>To get rid of it ice driver should answer for each VF message. In switchdev
>mode:
>- for adding/deleting VLAN driver should answer success without doing
>  anything to allow creating vlan device on VFs
>- for enabling/disabling VLAN stripping  and promiscuous mode driver
>  should answer not supported, this feature in switchdev can be only
>  set from host side
