CVE-2025-38271

In the Linux kernel, the following vulnerability has been resolved:

net: prevent a NULL deref in rtnl_create_link()

At the time rtnl_create_link() is running, dev->netdev_ops is NULL,
we must not use netdev_lock_ops() or risk a NULL deref if
CONFIG_NET_SHAPER is defined.

Use netif_set_group() instead of dev_set_group().
