  netlink linux: fix to append the netnsid netlink attr.

The attribute was being prepended to the netlink buffer, but
the function  nl_sock_transact_multiple__() expects to find the
netlink header as first to update the length, seq and pid fields.

This patch fixes to append the attribute instead of prepending it.
