[PATCH] ipw2200: Fix WPA network selection problem

Do not avoid APs with wpa_ie or rsn_ie if !ieee->wpa_enabled
There are broken APs out there that fill these elements even
though encryption is disnabled. Also, this breaks legit WEP to
WPA migration scenarious.

We add a checking to prohibite WPA configured STA trying to
associate with non-WPA supported APs.
