[PATCH v4 1/3] hw: Do not initialize MachineClass::is_default to 0

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

The MachineClass is already zeroed on creation.

Note: The code setting is_default=0 in hw/i386/pc_piix.c is
      different (related to compat options). When adding a
      new versioned machine, we want it to be the new default,
      so we have to mark the previous one as not default.
