PM/Hibernate: Fix memory shrinking
Commit d979677c4c0 ("mm: shrink_all_memory(): use sc.nr_reclaimed")
broke the memory shrinking used by hibernation, becuse it did not update
shrink_all_zones() in accordance with the other changes it made.
Fix this by making shrink_all_zones() update sc->nr_reclaimed instead of
overwriting its value.
This fixes http://bugzilla.kernel.org/show_bug.cgi?id=13058
