    NetApp: Return all iSCSI targets-portals

    NetApp iSCSI drivers use discovery mode for multipathing, which means
    that we'll fail to attach a volume if the IP provided for the discovery
    is not accessible from the host.

    Something similar would happen when using singlepath, as we are only
    trying to connect to one target/portal.

    This patch changes NetApp drivers so the return target_iqns,
    target_portals, and target_luns parameters whenever there are more than
    one option.
