Do not cleanup MKQL pool pages

[abyss7]

Changelog entry

While enabled the cleanup method cleans not only physically-allocated (RSS) pages, but also reserved ones that are never used. Thus we get a lot of "holes" inside mapped memory regions:

    3'000'000 - regions with cleanup
      100'000 - regions without cleanup
