mac80211: Scale down to non-HT association with TKIP/WEP as pairwise cipher
As TKIP is not updated to new security needs which arise when
TKIP is used to encrypt A-MPDU aggregated data frames, IEEE802.11n
does not allow any cipher other than CCMP (Which has new extensions
defined) as pairwise cipher between HT peers.
When such configuration (TKIP/WEP in HT) is forced, we still
associate in non-HT mode (11a/b/g).
