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
   4402	   1088	     38	   5528	   1598	fs/ocfs2/stackglue.o

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