tun: annotate access to queue->trans_start
[ Upstream commit 968a1a5d6541cd24e37dadc1926eab9c10aeb09b ]
Commit 5337824f4dc4 ("net: annotate accesses to queue->trans_start")
introduced a new helper, txq_trans_cond_update, to update
queue->trans_start using WRITE_ONCE. One snippet in drivers/net/tun.c
was missed, as it was introduced roughly at the same time.
