net: restore tx timestamping for accelerated vlans
Since commit 9b22ea560957de1484e6b3e8538f7eef202e3596
( net: fix packet socket delivery in rx irq handler )
We lost rx timestamping of packets received on accelerated vlans.
Effect is that tcpdump on real dev can show strange timings, since it gets rx timestamps
too late (ie at skb dequeueing time, not at skb queueing time)
