Fix the problem that the paging data is not displayed when searching the easycvr device management list page

There's user feedback , stay EasyCVR Device management list page , When searching for devices , Paging data is not displayed .

Technicians immediately checked the situation . It is found that , There is an error in the total number returned by the backend interface , This leads to the above problems .

It can be solved through the following methods ：

When the search criteria is passed in at the current end , The backend queries the corresponding number of devices , And then it goes back to the front end . The reference codes are as follows ：

devicescount, _ := cvrservice.GetDeviceService().CountDevice()
	devices := cvrservice.GetDeviceService().GetDevices(params["device"], params["q"], uint(start), uint(limit))
	if params["q"] != "" {
		devicescount1, err := cvrservice.GetDeviceService().CountDeviceByQ(params["q"])
		if err != nil {
			log.Printf("deviceService.GetDBDeviceByRoleID err :%v", err.Error())
			return
		}
		devicescount = devicescount1
	}

Query the front end again after modification , At this time, the number of devices and paging display have returned to normal .
