nvme-print-stdout: Do not show non reachable ns in namespace topology

If the host is connected to the target with two different hostnqn we can
have the situation where a namespace is only reachable via one ctrl and
a second namespace only by a different controller. Thus we should only
show a namespace in the topology if there is a path.
