kernel - Add needed ccfence and more error checks

* Add a cpu_ccfence() to PMAP_PAGE_BACKING_SCAN in order to prevent
  over-optimization of the ipte load by the compiler.

* Add machine-dependent assertion in the vm_page_free*() path to
  ensure that the page is not normally mapped at the time of the
  free.
