[PATCH net-next] net/ncsi: Define {add,kill}_vid callbacks for !CONFIG_NET_NCSI

[Samuel Mendoza-Jonas]

Patch "net/ncsi: Configure VLAN tag filter" defined two new callback
functions in include/net/ncsi.h, but neglected the !CONFIG_NET_NCSI
case. This can cause a build error if these are referenced elsewhere
without NCSI enabled, for example in ftgmac100:

>>> ERROR: "ncsi_vlan_rx_kill_vid" [drivers/net/ethernet/faraday/ftgmac100.ko] undefined!
>>> ERROR: "ncsi_vlan_rx_add_vid" [drivers/net/ethernet/faraday/ftgmac100.ko] undefined!

Add definitions for !CONFIG_NET_NCSI to bring it into line with the rest
of ncsi.h
