net: vlan: make non-hw-accel rx path similar to hw-accel
Now there are 2 paths for rx vlan frames. When rx-vlan-hw-accel is enabled, skb is untagged by NIC, vlan_tci is set and the skb gets into vlan code in __netif_receive_skb - vlan_hwaccel_do_receive. For non-rx-vlan-hw-accel however, tagged skb goes thru whole __netif_receive_skb, it's untagged in ptype_base hander and reinjected This incosistency is fixed by this patch. Vlan untagging happens early in __netif_receive_skb so the rest of code (ptype_all handlers, rx_handlers) see the skb like it was untagged by hw.
