Fix ESP32 reset during WiFi reconnect when mDNS is active (#24358)

Browse Source 
* Fix ESP32 reset during WiFi reconnect when mDNS is active

Explicitly call MDNS.end() before WiFi.disconnect() in support_wifi.ino.
This prevents a race condition or crash where the mDNS service attempts
to query or use the network interface while it is being torn down.

* Fix: removed lines added again.
