[ Upstream commit 43b5240ca6b33108998810593248186b1e3ae34a ]
"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")
