mm: remove khugepaged double thp vmstat update with CONFIG_NUMA=n
Johannes noticed the vmstat update is already taken care of by
khugepaged_alloc_hugepage() internally. The only places that are required
to update the vmstat are the callers of alloc_hugepage (callers of
khugepaged_alloc_hugepage aren't).
