    kernel - Fix i386 pmap bug
    
    * mpte will be NULL for KVM page table pages, there is no need to track
      the wire count.  Conditionalize-out the unwiring call.
    
    * This is believed to be (this time for sure to the third power!) the
      PG_BUSY crash that vsrinivas was getting on i386 related to paging
      in a swapped kernel pipe buffer.
