Kanchanapally, Vidyullatha 4ead7cfd5d Abort an ongoing scan before connect
Connect radio work is sometimes delayed for a considerable duration if
there is an ongoing scan radio work. To avoid these delays abort the
ongoing scan on that interface before queuing a connect request. Upon a
scan done indication from the driver, connect radio work will be
scheduled.
