usb: gadget: configfs: Constify struct config_item_type
'struct config_item_type' is not modified in this file.
Apparently, these structures are only used with
config_group_init_type_name() which takes a const struct config_item_type*
as a 3rd argument.
Constifying this structure moves some data to a read-only section, so
increase overall security, especially when the structure holds some
function pointers.
On a x86_64, with allmodconfig:
Before:
