    kernel - Update comments on PG_BUSY rules with page wirings
    
    * Adjust code comments to reflect that a vm_page's wire_count can transition
      from 1->0 without being busied under certain circumstances.
    
    * The pmap system is allowed to do this when removing pages because other
      references to the page are still present and there will be no race
      against a vm_page freeing operation.
