vlan: dont drop packets from unknown vlans in promiscuous mode

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.
