[MAC80211]: embed key conf in key, fix driver interface
This patch embeds the struct ieee80211_key_conf into struct ieee80211_key and thus avoids allocations and having data present twice. This required some more changes: 1) The removal of the IEEE80211_KEY_DEFAULT_TX_KEY key flag. This flag isn't used by drivers nor should it be since we have a set_key_idx() callback. Maybe that callback needs to be extended to include the key conf, but only a driver that requires it will tell. 2) The removal of the IEEE80211_KEY_DEFAULT_WEP_ONLY key flag. This flag is global, so it shouldn't be passed in the key conf structure. Pass it to the function instead. Also, this patch removes the AID parameter to the set_key() callback because it is currently unused and the hardware currently cannot know about the AID anyway. I suspect this was used with some hardware that actually selected the AID itself, but that functionality was removed. Additionally, I've removed the ALG_NULL key algorithm since we have ALG_NONE.
