lib/debugobjects: fix stat count and optimize debug_objects_mem_init
1. Var debug_objects_allocated tracks valid kmem_cache_alloc calls, so
track it in debug_objects_replace_static_objects. Do similar things in
object_cpu_offline.
2. In debug_objects_mem_init, there is no need to call function
cpuhp_setup_state_nocalls when debug_objects_enabled = 0 (out of
memory).
