git: kernel - Fix i386 pmap bug

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.
