[PATCH-for-6.2 v3 1/6] tests/unit/test-smp-parse: Restore MachineClass fields after modifying

["Philippe Mathieu-Daudé" <philmd@redhat.com>]

There is a single MachineClass object, registered with
type_register_static(&smp_machine_info). Since the same
object is used multiple times (an MachineState object
is instantiated in both test_generic and test_with_dies),
we should restore its internal state after modifying for
the test purpose.
