kernel - Fix pmap_change_attr() use cases.

* In DragonFly this function takes a page count, not a byte count.
  some calls were made with a byte count, others with a page count.

  Note that in FreeBSD this function takes a byte count, but after
  reviewing the use cases I decided to normalize it all to a page count.

* Fixes reported DRM issues.  Might also fix test branch ehci/ethernet
  panics due to memory corruption when DRM is loaded.
