mac80211: refactor association
Refactor the code to reserve an skb of the right size (instead of hoping 200 bytes are enough forever), and also put HT IE generation into an own function. Additionally, put the HT IE before the vendor-specific WMM IE. This still leaves things not quite ordered correctly, due to user-specified IEs, add a note about that for now.
