    Return WWN in multipath_id

    When we refactored the iSCSI connect mechanism we inadvertently changed
    the value returned for the "multipath_id" key.

    This patch fixes this and return the WWN as the value again.

    This value is used by the encryption mechanism and expects it to be the
    WWN.
