mm/sl[au]b: cleanup kmem_cache_alloc[_node]_trace()
Despite its name, kmem_cache_alloc[_node]_trace() is hook for inlined kmalloc. So rename it to kmalloc[_node]_trace(). Move its implementation to slab_common.c by using __kmem_cache_alloc_node(), but keep CONFIG_TRACING=n varients to save a function call when CONFIG_TRACING=n. Use __assume_kmalloc_alignment for kmalloc[_node]_trace instead of __assume_slab_alignement. Generally kmalloc has larger alignment requirements.
