[PATCH 7/8] s390: tape_core: 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
  11511     656      16   12183    2f97 drivers/s390/char/tape_core.o

File size After adding 'const':
   text    data     bss     dec     hex filename
  11575     592      16   12183    2f97 drivers/s390/char/tape_core.o
