To resolve the bug: #253.
The restore method should call the qemuProcessRefreshState method
to refreash the state of the devices.
Please also mention that this happens when restoring a VM from a save
image, as it's not clear from the commit message itself.
In general the commit message must be a standalone source of information
describing what's happening. This also means that the summary line
should be more descriptive.

So you are removing a comment which says that for migration this is
happening elsewhere without any justification or fix to the code.
The refresh in case of migration is happening in a different place for a
very good reason so we must keep it that way. This means you'll have to
introduce some form of logic which refreshes the state only when
restoring a save image.
