Ingo Molnar c1a0bf347c x86/mm/numa: Clean up numa_clear_kernel_node_hotplug()
So we fixed an overflow bug in numa_clear_kernel_node_hotplug():

  2b54ab3c66d4 ("x86/mm/numa: Fix memory corruption on 32-bit NUMA kernels")

... and the bug was indirectly caused by poor coding style,
such as using start/end local variables unnecessarily, which
lost the physaddr_t type.

So make the code more readable and try to fully comment all
the thinking behind the logic.

No change in functionality.
