mm/vmscan.c: fix types of some locals
In zone_reclaimable_pages(), `nr' is returned by a function which is declared as returning "unsigned long", so declare it such. Negative values are meaningless here. In zone_pagecache_reclaimable() 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.
