ipv6: Silence privacy extensions initialization
When a network namespace is created (via CLONE_NEWNET), the loopback interface is automatically added to the new namespace, triggering a printk in ipv6_add_dev() if CONFIG_IPV6_PRIVACY is set. This is problematic for applications which use CLONE_NEWNET as part of a sandbox, like Chromium's suid sandbox or recent versions of vsftpd. On a busy machine, it can lead to thousands of useless "lo: Disabled Privacy Extensions" messages appearing in dmesg. It's easy enough to check the status of privacy extensions via the use_tempaddr sysctl, so just removing the printk seems like the most sensible solution.
