v1 -> v2:
- Renamed the flag from 'LIVE' to 'POWERED'. Live can be interpreted
differently i.e if it means just IFF_UP/powered or if it means
connected. POWERED is more accurate to what this feature does.
- Reworked the logic to check if individual interfaces are busy
rather than globally. Simply checking local->scanning/roc_list
was a large hammer, and puts limitations in that aren't needed.
Now roc_list is traversed and only returns -EBUSY if the actual
interface has ROC work. Similarly the scanning sdata is checked
and -EBUSY is returned if it matches the sdata for which the
address is being changed.
- Only P2P_CLIENT/STATION iftypes are allowed to do a powered address
change. I personally see no reason this is needed for other iftypes
but if we want others to be supported I'm fine adding more.
- Check return of drv_add_interface
