Hangbin Liu 1a63730fb3 ipv6: sr: fix invalid unregister error path
[ Upstream commit 160e9d2752181fcf18c662e74022d77d3164cd45 ]

The error path of seg6_init() is wrong in case CONFIG_IPV6_SEG6_LWTUNNEL
is not defined. In that case if seg6_hmac_init() fails, the
genl_unregister_family() isn't called.

This issue exist since commit 46738b1317 ("ipv6: sr: add option to control
lwtunnel support"), and commit 5559cea2d5aa ("ipv6: sr: fix possible
use-after-free and null-ptr-deref") replaced unregister_pernet_subsys()
with genl_unregister_family() in this error path.

Fixes: 46738b1317 ("ipv6: sr: add option to control lwtunnel support")
