batman-adv: move batadv_slide_own_bcast_window to bat_iv_ogm.c
batadv_slide_own_bcast_window() is used only in bat_iv_ogm.c and it is currently touching only batman_iv specific attributes. Move it into bat_iv_ogm.c and make it static. Signed-off-by: Antonio Quartulli <antonio@open-mesh.com> Signed-off-by: Marek Lindner <lindner_marek@yahoo.de>
