tracing/slab: Move kmalloc tracepoint out of inline code

The tracepoint for kmalloc is in the slab inlined code which causes
every instance of kmalloc to have the tracepoint.

This patch moves the tracepoint out of the inline code to the
slab C file, which removes a large number of inlined trace
points.

This also has a nice impact on size.
