Eric Dumazet 207501a986 ipv6/sit: use DEV_STATS_INC() to avoid data-races
[ Upstream commit cb34b7cf17 ]

syzbot/KCSAN reported that multiple cpus are updating dev->stats.tx_error
concurrently.

This is because sit tunnels are NETIF_F_LLTX, meaning their ndo_start_xmit()
is not protected by a spinlock.

While original KCSAN report was about tx path, rx path has the same issue.
