Roger Luethi noticed packets for unknown VLANs getting silently dropped
even in promiscuous mode.
Check for promiscuous mode in __vlan_hwaccel_rx() and vlan_gro_common()
before drops.
As suggested by Patrick, mark such packets to have skb->pkt_type set to
PACKET_OTHERHOST to make sure they are dropped by IP stack.
