mac80211: remove dead code, clean up

Browse Source 
With mac80211 now always controlled by an external SME,
a lot of code is dead -- SSID, BSSID, channel selection
is always done externally, etc. Additionally, rename
IEEE80211_STA_TKIP_WEP_USED to IEEE80211_STA_DISABLE_11N
and clean up the code a bit.
