batman-adv: a delayed_work has to be initialised once
A delayed_work struct does not need to be initialized each every time before being enqueued. Therefore the INIT_DELAYED_WORK() macro should be used during the initialization process only. Signed-off-by: Antonio Quartulli <ordex@autistici.org> Signed-off-by: Marek Lindner <lindner_marek@yahoo.de>
