mac80211: support hw scan while idle
Currently, mac80211 goes to idle-off before starting a scan. However, some devices that implement hw scan might not need going idle-off in order to perform a hw scan, and thus saving some energy and simplifying their state machine. (Note that this is also the case for sched scan - it currently doesn't make mac80211 go idle-off) Add a new flag to indicate support for hw scan while idle.
