Fix build with !HUGETLBFS

I stupidly broke the case of CONFIG_HUGETLBFS=n when doing the conversion to vm_flags_t in commit ca16d14 ("mm: don't access vm_flags as 'int'"). And my 'allyesconfig' build didn't find it, for obvious reasons.. Include <linux/mm_types.h> in <linux/hugetlb.h>. The problem could have been avoided by just turning the hugetlb_file_setup() error wrapper into a macro, but mm_types.h is a reasonable include in this file.
