[libvirt] [PATCH] qemudDomainRestore: handle a case of virDomainSaveStatus failure

For each of the other uses of virDomainSaveStatus, the caller handles failure. Here it was ignored. At first I was inclined to simply "goto endjob;", like a few other uses in this file, but probing a bit, I found a few paths by which it could fail with no diagnostic whatsoever. And even if we've already emitted a diagnostic about some lower-level failure, it probably helps the user to know what high-level operation failed.
