The removal of the batched object freeing has caused the debug_objects_freed to become read-only, and the reading is inside an ifdef, so gcc warns that it is completely unused without CONFIG_DEBUG_FS:
lib/debugobjects.c:71:14: error: 'debug_objects_freed' defined but not used [-Werror=unused-variable]
Assuming we are still interested in this number, this adds back code to keep track of the freed objects.
