AP: Support disconnect with MLD
I've setup a 2G AP in WPA-PSK/SAE mixed mode. All clients which using WPA-PSK will be disconnect after a few seconds:

This is repeated continuously. There is no stable connection.
I've setup a 5G AP in WPA-EAP mode using the internal radius server. Clients (windows 10) can connect and the connection is stable.
If I reboot a client, hostapd crashes with a page fault. Output from gdb:
Core was generated by `/usr/sbin/hostapd -s -g /var/run/hostapd/global'.
Program terminated with signal SIGSEGV, Segmentation fault.

I'm using hostap on OpenWrt. OpenWrt does update hostap to the version from 2025/01/01.
If I revert the mentioned commit only, I see no issues.
