mm: sysctl: fix missing numa_stat when !CONFIG_HUGETLB_PAGE
"numa_stat" should not be included in the scope of CONFIG_HUGETLB_PAGE, if
CONFIG_HUGETLB_PAGE is not configured even if CONFIG_NUMA is configured,
"numa_stat" is missed form /proc. Move it out of CONFIG_HUGETLB_PAGE to
fix it.
Fixes: 4518085e127d ("mm, sysctl: make NUMA stats configurable")
