Pull last minute virtio fixes from Michael S. Tsirkin:
 "Here are a couple of last minute virtio fixes for 3.4.  Hope it's not
  too late yes - I might have tried too hard to make sure the fix is
  well tested.

  Fixes are by Amit and myself.  One fixes module removal and one
  suspend of a VM, the last one the handling of out of memory condition.

  They are thus very low risk as most people never hit these paths, but
  do fix very annoying problems for people that do use the feature.
