x86, mm: Correct the implementation of is_untracked_pat_range()
The semantics the PAT code expect of is_untracked_pat_range() is "is
this range completely contained inside the untracked region." This
means that checkin 8a27138924f64d2f30c1022f909f74480046bc3f was
technically wrong, because the implementation needlessly confusing.
The sane interface is for it to take a semiclosed range like just
about everything else (as evidenced by the sheer number of "- 1"'s
removed by that patch) so change the actual implementation to match.
