mac80211: Make sure non-HT connection when IEEE80211_STA_TKIP_WEP_USE…

…D is set

It is possible that some broken AP might send HT IEs in it's
assoc response even though the STA has not sent them in assoc req
when WEP/TKIP is used as pairwise cipher suite. Also it is important
to check this bit before enabling ht mode in beacon receive path.
