mac80211: generalise management work a bit
As a first step of generalising management work, this renames a few things and puts more information directly into the struct so that auth/assoc need not access the BSS pointer as often -- in fact it can be removed from auth completely. Also since the previous patch made sure a new work item is used for association, we can make the different data a union.
