mm/hugetlb: fix incorrect update of max_huge_pages

Patch series "A few fixup patches for hugetlb".

This series contains a few fixup patches to fix incorrect update of
max_huge_pages, fix WARN_ON(!kobj) in sysfs_create_group() and so on.
More details can be found in the respective changelogs.

This patch (of 6):

There should be pages_per_huge_page(h) /
pages_per_huge_page(target_hstate) pages incremented for
target_hstate->max_huge_pages when page is demoted.  Update max_huge_pages
accordingly for consistency.
