Fix extra indention in firewall views.py code

[Lin Hua Cheng]

It is not obvious in here, but there are 8 spaces instead of 4 space in the indent of the code inside the method

https://github.com/openstack/horizon/blob/master/openstack_dashboard/dashboards/project/firewalls/views.py#L175

    @memoized.memoized_method
    def _get_object(self, *args, **kwargs):
            policy_id = self.kwargs['policy_id']
            try:
                policy = api.fwaas.policy_get(self.request, policy_id)
                return policy
            except Exception:
                redirect = self.success_url
                msg = _('Unable to retrieve policy details.')
                exceptions.handle(self.request, msg, redirect=redirect)
