devicelist.cgi returns invalid xml if device_id is set

[Tommi2Day]

Thanks for this great addon

I think I found a small issue running raspberrymatic v3.73.9.20240130 with xml-api Addon 2.3

I call https://ccu.xxx/addons/xmlapi/devicelist.cgi?sid=xxx&device_id=4740,4763 and it returns an invalid xml (for golang)

<?xml version='1.0' encoding='ISO-8859-1' ?><deviceList><device name='Bewegungsmelder Garage' address='000955699D3D84' ise_id='4740' interface='HmIP-RF' device_type='HmIP-SMO' ready_config='true'><channel name='Bewegun

[Sat, 17 Feb 2024 14:13:14 CET] ERROR devicelist returned error: XML syntax error on line 1: element <device> closed by </deviceList>

the closing </device> before </devicelist> is missed.

Without the device_id parameter it has the correct output

The problem occurs if you enter the ise_id of a channel and not of a device as device_id
