Alexander Lobakin 8be33ecfc1 net: skb_vlan_untag(): don't reset transport offset if set by GRO layer
Similar to commit fda55eca5a
("net: introduce skb_transport_header_was_set()"), avoid resetting
transport offsets that were already set by GRO layer. This not only
mirrors the behavior of __netif_receive_skb_core(), but also makes
sense when it comes to UDP GSO fraglists forwarding: transport offset
of such skbs is set only once by GRO receive callback and remains
untouched and correct up to the xmitting driver in 1:1 case, but
becomes junk after untagging in ingress VLAN case and breaks UDP
GSO offload. This does not happen after this change, and all types
of forwarding of UDP GSO fraglists work as expected.

Since v1 [1]:
 - keep the code 1:1 with __netif_receive_skb_core() (Jakub).
