qemu: managedsave: Don't spam logs with warnings about corrupted image

Even successful start of a VM from a managed save image would spam the
logs with the following message:

Unable to restore from managed state [path]. Maybe the file is
corrupted?

Re-arrange the logic to output the warning only when the image is
corrupted.

The flaw was introduced in commit cfc28c66.
