[PATCH 1/2] configfs: Constify ct_group_ops in struct config_item_type

Make 'ct_group_ops' const in struct config_item_type.
This allows constification of many structures which hold some function
pointers.

Compile tested only files that explicitly use ct_group_ops.

The script used for that is:
while IFS= read -r -d '' file; do
obj="${file%.c}.o" ; echo -e "\nCompiling $file" ; make "$obj"
done < <(git grep --name-only -z ct_group_ops '*.c')
