[PATCH v2] selinux label: restore all labels when some labels fail to set

[Jin Yan <jinyan12@xxxxxxxxxx>]

When migration fails, qemuMigrationDstPrepareAny will call qemuProcessStop
to restore labels only after all labels are successfully set. If some labels
fail to set, the labels that have been set will not be restored.
