I haven't been able to reproduce this exact code path, but taken into
account that this is actually iterating through the BSS table list that
got corrupted (and is now fixed), wpa_s->bss_id, I would assume this
ended up using freed memory reading of bss->id here failed since the
list iteration got some random data for the bss pointer. In other words,
I'm assuming that this has been resolved, too.
