attribute_groups are not supposed to change at runtime. All functions
working with attribute_groups provided by <linux/transport_class.h>
work with const attribute_group. So mark the non-const structs as const.

File size before:
   text    data     bss     dec     hex filename
  34122    1932       4   36058    8cda drivers/scsi/scsi_transport_fc.o

File size After adding 'const':
   text    data     bss     dec     hex filename
  34186    1868       4   36058    8cda drivers/scsi/scsi_transport_fc.o
