mac80211: fix ibss race
When a scan completes, we call ieee80211_sta_find_ibss(), which is also called from other places. When the scan was done in software, there's no problem as both run from the single-threaded mac80211 workqueue and are thus serialised against each other, but with hardware scan the completion can be in a different context and race against callers of this function from the workqueue (e.g. due to beacon RX). So instead of calling ieee80211_sta_find_ibss() directly, just arm the timer and have it fire, scheduling the work, which will invoke ieee80211_sta_find_ibss() (if that is appropriate in the current state).
