Tested on both sd8686 (v9 fw) and usb8388 (v5 OLPC fw).  Switching
between WEP and WPA-PSK on-the-fly works as expected with this patch.

Though maybe we want to add a comment about this specific issue that
says something like:

/* v10 FW wants WPA keys to be set/cleared after WEP key operations,
 * otherwise it will fail to correctly associate to WEP networks.
 * Other firmware versions don't appear to care.
