[PATCH] fs: GFS2: constify attribute_group structures.

[Arvind Yadav]

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
   5259    1344       8    6611    19d3 fs/gfs2/sys.o

File size After adding 'const':
   text    data     bss     dec     hex filename
   5371    1216       8    6595    19c3 fs/gfs2/sys.o
