CVE-2026-63986

ethtool: tsinfo: don't pass ERR_PTR to genlmsg_cancel on prepare failure

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

ethtool: tsinfo: don't pass ERR_PTR to genlmsg_cancel on prepare failure

The goto err label leads to:

	genlmsg_cancel(skb, ehdr);
	return ret;

If ethnl_tsinfo_prepare_dump() failed, it has not started a genlmsg.
There's nothing to cancel, and passing an error pointer to
genlmsg_cancel() would cause a crash.
