https://bugzilla.redhat.com/show_bug.cgi?id=1181182 When we meet error in qemuMigrationPrepareAny and goto cleanup with rc < 0, we forget clear the priv->origname and this will make this vm migrate fail next time because leave a wrong origname in priv, and will Generate a wrong cookie when do migrate next time. This patch will make priv->origname is NULL when migrate fail in target host.
