route/link: remove rtnl_link_inet6_set_conf() API

It's not clear how this API is useful. I don't think that kernel accepts
netlink requests to change the settings. So constructing a libnl3 object
in the user application seems not useful.

Also, because of the difficulty that DEVCONF_MAX is depending on the
current kernel, and changing. We need to improve how to handle the
option, and a rtnl_link_inet6_set_conf() only makes that more confusing.

The same is the case for rtnl_link_inet6_set_flags(), but that API
already exists, while rtnl_link_inet6_set_conf() is still new and
unreleased.
