mv_machine_learning: initialize backend type correctly

[Issue type] : bug fix

Initialize _backendType member variable correctly with
MV_INFERENCE_BACKEND_NONE.

This patch fixes a issue that loading default backend type from meta config
file is skipped if user doesn't call mv_task_name_set_engine().

See below parseConfigFile function code in MvMlConfig.cpp,
	if (_backendType == MV_INFERENCE_BACKEND_NONE) {
		ret = config->getIntegerAttribute(MV_BACKEND_TYPE, &_backendType);
		if (ret != MEDIA_VISION_ERROR_NONE)
			throw InvalidOperation("Fail to get backend engine type.");
	}
