mac80211: fix powersave
Some of the recent MLME rework I did broke powersave because the ps_sdata isn't assigned at the right time, and the work item wasn't removed from the list before calling ieee80211_recalc_ps(). To be more specific, this broke the case where you'd enabled PS before associating, either automatically or with iwconfig.
