Subject: [PATCH] HWPOISON: Fix page count leak in hwpoison late kill in
 do_swap_page

When returning due to a poisoned page drop the page count.

It wasn't a fatal problem because noone cares about the page count
on a poisoned page (except when it wraps), but it's cleaner to fix it.

Pointed out by Linus.
