Currently if anything goes wrong while we're configuring the namespace network with --config-net, we'll just ignore it and carry on. This might lead to a silently unconfigured or misconfigured namespace environment. For simple "set" operations based on nl_do() we can now detect failures reported via netlink. Propagate those errors up to pasta_ns_conf() and report them usefully.
