ec2 api shoud check the 'max_count' and 'min_count' para in run_instances

[lizheming]

the code:
def run_instances(self, context, **kwargs):
        min_count = int(kwargs.get('min_count', 1))
        ...
       (instances, resv_id) = self.compute_api.create(context,
            instance_type=obj_base.obj_to_primitive(flavor),
            image_href=image_uuid,
            max_count=int(kwargs.get('max_count', min_count)),
            min_count=min_count,
        ...

there is no checking to 'min_count' and 'max_count',
if 'min_count'>max_count, it will be error.
