Validate WEP key lengths based on driver capabilities

Browse source 
The nl80211 driver interface does not allow 128-bit WEP to be used
without a vendor specific cipher suite and no such suite is defined for
this purpose. Do not accept WEP key length 16 for nl80211 driver
interface forn ow. wext-interface can still try to use these for
backwards compatibility.
