virtio_balloon: update_balloon_size(): update correct field

According to the virtio spec, the device configuration field
that should be updated after an inflation or deflation
operation is the 'actual' field, not the 'num_pages' one.

Commit 855e0c5288 swapped them
in update_balloon_size(). Fix it.
