[PATCH] tools/vm/page-types.c: fix "kpagecount returned fewer pages than expected" failures

[Anthony Yznaga]

Because kpagecount_read() fakes success if map counts are not being
collected, clamp the page count passed to it by walk_pfn() to the pages
value returned by the preceding call to kpageflags_read().
