x86/mm/64: Rename the register_page_bootmem_memmap() 'size' parameter to 'nr_pages'
register_page_bootmem_memmap()'s 3rd 'size' parameter is named
in a somewhat misleading fashion - rename it to 'nr_pages' which
makes the units of it much clearer.
Meanwhile rename the existing local variable 'nr_pages' to
'nr_pmd_pages', a more expressive name, to avoid conflict with
new function parameter 'nr_pages'.
(Also clean up the unnecessary parentheses in which get_order() is called.)
