In GIWENCODE, NOKEY is supposed to mean that the key is write-only and
can't be read out of the card's registers or firmware. This one came
over when harmonizing the libertas handlers with airo. Since libertas
always caches the keys (both WEP and WPA) internally, it doesn't ever
need to set NOKEY in GIWENCODE because they are always available.
You can really just take that NOKEY line out completely, you don't need
anything else in this patch.
