[PATCH] rsi: fix broken AP mode due to unwanted encryption

In AP mode WPA-PSK connections were not established.

The reason was that the AP was sending the first message
of the 4 way handshake encrypted, even though no key had
(correctly) yet been set.

Fix this by adding an extra check that we have a key.

The redpine downstream out of tree driver does it this way too.
