Eric Dumazet 30e77e3ee9 ipvlan: properly track tx_errors 
[ Upstream commit ff672b9ffe ]

Both ipvlan_process_v4_outbound() and ipvlan_process_v6_outbound()
increment dev->stats.tx_errors in case of errors.

Unfortunately there are two issues :

1) ipvlan_get_stats64() does not propagate dev->stats.tx_errors to user.

2) Increments are not atomic. KCSAN would complain eventually.

Use DEV_STATS_INC() to not miss an update, and change ipvlan_get_stats64()
to copy the value back to user.

Fixes: 2ad7bf3638 ("ipvlan: Initial check-in of the IPVLAN driver.")
