net: netconsole: Constify struct config_item_type
'struct config_item_type' is not modified in this driver.
This structure is only used with config_group_init_type_name() which takes
a const struct config_item_type* as a 3rd argument.
This also makes things consistent with 'netconsole_target_type' witch is
already const.
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:
======

After:
