We now detect errors on netlink "set" operations while configuring the pasta namespace with --config-net. However in many cases rather than a simple "set" we use a more complex "dup" function to copy configuration from the host to the namespace. We're not yet properly detecting and reporting netlink errors for that case. Change the "dup" operations to propagate netlink errors to their caller, pasta_ns_conf() and report them there.
