mm/page_alloc.c: remove unused variable in free_area_init_core()

Commit febd5949e134 ("mm/memory hotplug: init the zone's size when
calculating node totalpages") refines the function
free_area_init_core().

After doing so, these two parameters are not used anymore.

This patch removes these two parameters.
