revert "topology: add support for node_to_mem_node() to determine the fallback node"
This reverts commit ad2c8144418c6a81cefe65379fd47bbe8344cef2.
The function node_to_mem_node() was introduced by that commit for use in SLUB
on systems with memoryless nodes, but it turned out to be unreliable on some
architectures/configurations and a simpler solution exists than fixing it up.
Thus commit 0715e6c516f1 ("mm, slub: prevent kmalloc_node crashes and
memory leaks") removed the only user of node_to_mem_node() and we can
revert the commit that introduced the function.
