[PATCH mm-unstable 1/2] mm/mm_init: rename __init_reserved_page_zone to __init_page_from_nid

[Mike Rapoport]

From: "Mike Rapoport (Microsoft)" <rppt@xxxxxxxxxx>

__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.
