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.
