powerpc/mm: Fix build error with hugetlfs disabled
arch/powerpc/mm/slice.c:704:5: error: expected identifier or ‘(’ before numeric constant
int is_hugepage_only_range(struct mm_struct *mm, unsigned long addr,

This got introduced via 1217d34b531c76362217057ca70a8ce8950574e0
"powerpc: Ensure global functions include their prototype". We
started including linux/hugetlb.h with that patch and now we have
#define is_hugepage_only_range(mm, addr, len) 0
with hugetlbfs disabled.
Fixes: 1217d34b531c ("powerpc: Ensure global functions include their prototype")
