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.
