dev: Acquire netdev_rename_lock before restoring dev->name in dev_change_name().
[ Upstream commit e361560a7912958ba3059f51e7dd21612d119169 ]
The cited commit forgot to add netdev_rename_lock in one of the
error paths in dev_change_name().
Let's hold netdev_rename_lock before restoring the old dev->name.
Fixes: 0840556e5a3a ("net: Protect dev->name by seqlock.")
