mac80211: fix WMM AP settings application
My commit 77fdaa12 Author: Johannes Berg <johannes@sipsolutions.net> Date: Tue Jul 7 03:45:17 2009 +0200 mac80211: rework MLME for multiple authentications inadvertedly broke WMM because it removed, along with a bunch of other now useless initialisations, the line initialising sdata->u.mgd.wmm_last_param_set to -1 which would make it adopt any WMM parameter set. If, as is usually the case, the AP uses WMM parameter set sequence number zero, we'd never update it until the AP changes the sequence number. Add the missing initialisation back to get the WMM settings from the AP applied locally.
