Johannes Weiner bc43f75cd9 mm: fix pageref leak in do_swap_page() 
By the time the memory cgroup code is notified about a swapin we
already hold a reference on the fault page.

If the cgroup callback fails make sure to unlock AND release the page
reference which was taken by lookup_swap_cach(), or we leak the reference.
