reconnect: do not initialize iscsi to old_iscsi, use old_iscsi if appropriate

O-Subject: [PATCH 05/11] reconnect: do not initialize iscsi to old_iscsi, use old_iscsi if appropriate
Bugzilla: 1026820

Makes it clearer that logging has to be done on the existing context,
since the "iscsi" pointer will not survive iscsi_reconnect.
