mm/slab_common: unify NUMA and UMA version of tracepoints

Browse source 
Drop kmem_alloc event class, rename kmem_alloc_node to kmem_alloc, and
remove _node postfix for NUMA version of tracepoints.

This will break some tools that depend on {kmem_cache_alloc,kmalloc}_node,
but at this point maintaining both kmem_alloc and kmem_alloc_node
event classes does not makes sense at all.
