    Two cleanups:
    * si->cur_comp, si->cur_pg where always calculated after
      the call to ore_calc_stripe_info() with the help of
      _dev_order(...). But these are already calculated by
      ore_calc_stripe_info() and can be just set there.
      (This is left over from the time that si->cur_comp, si->cur_pg
       were only used by raid code, but now the main loop manages
       them anyway even though they are ultimately not used in
       none raid code)
    
    * si->cur_comp - For the very last stripe case, was set inside
      _ore_add_parity_unit(). This is not clear and will be wrong
      for coming raid6 so move this to only caller. Now si->cur_comp
      is only manipulated within _prepare_for_striping(), always next
      to the manipulation of cur_dev.
      Which is much easier to understand and follow.
