This does not look like the correct place to do this. This function is
called only if the station send Deauthentication frame to the AP. This
may not happen, i.e., the station may use Disassociation frame or just
go out of range from the AP without sending any frame. If this type of
log information is desired, I would assume it would be desired for all
different ways of a station getting disconnected. In other words, this
would need to be done in the same place as account_sta_stop().

I know you mentioned that you did not want to modify the RADIUS
accounting code for this, but that would likely be the best place for
doing this. This takes care of the counter wrapping and there is already
a hostapd_logger() call in accounting_sta_update_stats() for that
