[PATCH 6.18 0203/1250] netlabel: fix IPv6 unlabeled address add error handling

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

6.18-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Chenguang Zhao <zhaochenguang@kylinos.cn>

[ Upstream commit 56872b930feee7ae07b9720ca950dd9fa65596ee ]

netlbl_unlhsh_add_addr6() always returned zero after
netlbl_af6list_add(), masking failures such as duplicate
IPv6 static label entries.
