[PATCH 1/8] s390: zcrypt_queue: constify attribute_group structures.

[Arvind Yadav]

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.

File size before:
   text	   data	    bss	    dec	    hex	filename
   1361	     96	      0	   1457	    5b1	s390/crypto/zcrypt_queue.o

File size After adding 'const':
   text	   data	    bss	    dec	    hex	filename
   1425	     32	      0	   1457	    5b1	s390/crypto/zcrypt_queue.o
