ocfs2: constify attribute_group structures
attribute_groups are not supposed to change at runtime. All functions
working with attribute_groups provided by <linux/sysfs.h> work with
const attribute_group. So mark the non-const structs as const.
File size before:
text data bss dec hex filename

File size After adding 'const':
text data bss dec hex filename
4442 1024 38 5504 1580 fs/ocfs2/stackglue.o
