[PATCH 2/2] mm: fix declarations of nr, delta and nr_pagecache_reclaimable

[Alexandru Moise]

The nr variable is meant to be returned by a function which is
declared as returning "unsigned long", so declare nr as such.

Lower down we should also declare delta and nr_pagecache_reclaimable
as being unsigned longs because they're used to store the values
returned by zone_page_state() and zone_unmapped_file_pages() which
also happen to return unsigned integers.
