kmemleak: Initialise kmemleak after debug_objects_mem_init()
commit 9b090f2da85bd0df5e1a1ecfe4120b7b50358f48 upstream.
Kmemleak frees objects via RCU and when CONFIG_DEBUG_OBJECTS_RCU_HEAD
is enabled, the RCU callback triggers a call to free_object() in
lib/debugobjects.c. Since kmemleak is initialised before debug objects
initialisation, it may result in a kernel panic during booting. This
patch moves the kmemleak_init() call after debug_objects_mem_init().
