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.
