mm/mm_init: rename __init_reserved_page_zone to __init_page_from_nid

__init_reserved_page_zone() function finds the zone for pfn and nid and
performs initialization of a struct page with that zone and nid.  There is
nothing in that function about reserved pages and it is misnamed.

Rename it to __init_page_from_nid() to better reflect what the function
does.
