storage: Set ret = -1 on failures in virStorageBackendUpdateVolTargetInfo

Browse Source 
While processing the volume for lseek, virFileReadHeaderFD, and
virStorageFileGetMetadataFromBuf - failure would cause an error,
but ret would not be set. That would result in an error message being
sent, but successful status being returned.
