[Bridge] [PATCH net-next] net: bridge: replace __vlan_hwaccel_put_tag with skb_vlan_push

[Kangmin Park]

br_handle_ingress_vlan_tunnel() is called in br_handle_frame() and
goto drop when br_handle_ingress_vlan_tunnel() return non-zero.

But, br_handle_ingress_vlan_tunnel() always return 0. So, the goto
routine is currently meaningless.

However, paired function br_handle_egress_vlan_tunnel() call
skb_vlan_pop(). So, change br_handle_ingress_vlan_tunnel() to call
skb_vlan_push() instead of __vlan_hwaccel_put_tag(). And return
the return value of skb_vlan_push().
