[PATCH 4/5] qemu: Refresh state after restore from a save image

When restoring a domain from a save image, we need to query QEMU for some runtime information that is not stored in status XML, or even if it is, it's not parsed (e.g. virtio-mem actual size, or soon rx-filters for macvtaps). During migration, this is done in qemuMigrationDstFinishFresh(), or in case of newly started domain in qemuProcessStart(). Except, the way that the code is written, when restoring from a save image (which is effectively a migration), the state is never refreshed, because qemuProcessStart() sees incoming migration so it does not refresh the state thinking it'll be done in the finish phase. But restoring from a save image has no finish phase. Therefore, refresh the state explicitly after the domain was restored but before vCPUs are resumed.
