[PATCH 1/4] scsi: scsi_transport_iscsi: 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
  40380   10422      44   50846    c69e scsi/scsi_transport_iscsi.o

File size After adding 'const':
   text    data     bss     dec     hex filename
  40764   10070      44   50878    c6be scsi/scsi_transport_iscsi.o
