    kernel: add bare_cat_owner(), use when deleting CATs
    
    Ditto for bare_spd_owner().
    
    When deleting a CAT/SPD check to see if some other SPD exists that
    should instead be restored.  Note that callers trying to perform
    the same check (but seemingly fail) have been made redundant.
    
    fix #944
