I suspect the AP isn't sending Accounting-Stop in this situation, but 
you can confirm that by running freeradius in debug mode (-X) and 
watching the screen, or running a packet sniffer such as wireshark or 
tcpdump.

If the AP isn't sending Accounting-Stop, and there's no way you can get 
a better AP that does, I guess you could periodically run a script from 
cron to log into the AP's web interface and grab the list of MAC 
addresses and compare against what your accounting database thinks are 
open sessions...
