From: Andrei Otcheretianski <[email protected]> Don't use cancel_delayed_work_sync() inside the channel switch notifications as they are handled synchronously as part of the RX path. Fix that by replacing it with cancel_delayed_work(). This should be safe as we don't really care whether the work is already started and in such case we would disconnect anyway.
