Description of problem:

As described in https://github.com/open-iscsi/open-iscsi/issues/228

Probably fixed by https://github.com/open-iscsi/open-iscsi/pull/292

While target being unavailable, restarting iscsid leads to stuck sessions

1. iscsiadm -m node
   iscsiadm: No records found
2. iscsiadm -m discoverydb
   #
3. iscsiadm -m node -u
   Logging out of session [sid: 25, target: iqn.2017-11.com.redhat:params-test, portal: 127.0.0.1,3260]
   iscsiadm: Could not logout of [sid: 25, target: iqn.2017-11.com.redhat:params-test, portal: 127.0.0.1,3260].
   iscsiadm: initiator reported error (32 - target likely not connected)
   iscsiadm: Could not logout of all requested sessions

journalctl:
iscsid: connect to 127.0.0.1:3260 failed (Connection refused)
...repeated....
