Subject: [PATCH 5/6] iscsiroot: try targets only once

In multipath scenarios, "iscsiadm -m node" may contain
several records with the same target.
There's no point in trying "iscsiadm --login" multiple
time for the same target, through the same portal.

Moreover, warn if the desired target is not on the node
list.
