Update RS Skipped cards uses wrong enum to register to phase

During initialization of the phase time records the code uses the wrong enum to register the "Skipped Cards" to the "Update RS" logging structure.

I.e.
      _gc_par_phases[UpdateRS]->link_thread_work_items(_update_rs_skipped_cards, ScanRSSkippedCards);

which should be

    _gc_par_phases[UpdateRS]->link_thread_work_items(_update_rs_skipped_cards, UpdateRSSkippedCards);

Since the value of ScanRSSkippedCards equals UpdateRSSkippedCards there is no harm.
