slub: cure list_slab_objects() from double fix
According to Christopher Lameter two fixes have been merged for the same
problem. As far as I can tell, the code does not acquire the list_lock
and invoke kmalloc(). list_slab_objects() misses an unlock (the
counterpart to get_map()) and the memory allocated in free_partial()
isn't used.
Revert the mentioned commit.
