[PATCH 5/5] mm: hugetlb: constify attribute_group structures.

[Arvind Yadav <arvind.yadav.cs@gmail.com>]

attribute_group are not supposed to change at runtime. All functions
working with attribute_group provided by <linux/sysfs.h> work with
const attribute_group. So mark the non-const structs as const.
