Dell SC driver not returning all iSCSI MP paths

[Tom Swanson]

The Dell SC iSCSI driver is not reporting all target portals and iqns and luns. Depending on how domains (SC domains) are setup the Dell SC driver might not report all available paths. Also the best path might not have been selected. This should be fine in Kilo but would be a problem in multipath environments.

    Reworked Dell SC iSCSI target portal return

    On initialize_connection the code to determine the portal, lun and
    iqn info to return could skip ports and potentially not return the
    best portal choice. In the case of multipath being enabled not all
    ports would be returned.

    Also changed a LOG.debug to a LOG.info in initialize_connection.
