Upstream-Description:

zdev: Handle special case in if-case

As preparation for a following commit reorder the path logic in function
             zfcp_lun_st_get_active_attrib_path(). This then allows to handle
             subsequent special cases more easily. Additionally it also enhances the
             readability of the expression.
