[PATCH v6 02/10] mm/memmap_init: Update variable name in memmap_init_zone

[David Hildenbrand]

From: "Aneesh Kumar K.V" <aneesh.ku...@linux.ibm.com>

The third argument is actually number of pages. Changes the variable name
from size to nr_pages to indicate this better.

No functional change in this patch.
