Fernando Fernandez Mancera 17dc3b245d ipv6: fix missing notification for ignore_routes_with_linkdown 
When changing the ignore_routes_with_linkdown sysctl for a specific
interface, the RTM_NEWNETCONF netlink notification was not being emitted
to userspace. Fix this by emitting the notification when needed.

In addition, fix bogus return value for successful "all" and specific
interface write operation leading to a wrong reset of the position
pointer.

Fixes: 35103d1117 ("net: ipv6 sysctl option to ignore routes when nexthop link is down")
