mm: memory_hotplug: remove second __nr_to_section in register_page_bootmem_info_section()
In register_page_bootmem_info_section() we call __nr_to_section() in
order to get the mem_section struct at the beginning of the function.
Since we already got it, there is no need for a second call to
__nr_to_section().
