virtio-balloon: reset the statistic timer to load device

Browse source 
If before loading snapshot we had set the timer of statistics, then after
applying snapshot the expiry time would be irrelevant for the restored
state of the virtual clocks. A simple fix is just to restart the timer
after loading snapshot.

For the user it may look like a long delay of statistics update after switch
to the snapshot.
