batman-adv: fix logic error in batadv_v_ogm_forward
Commit Message
From: Simon Wunderlich <simon.wunderlich@open-mesh.com>
My latest restructure attempt of the BATMAN v forward function
introduced a regression, causing kernel crashes when an OGM is
forwarded. This patch fixes it.
Fixes: 30c96bc787 ("batman-adv: move and restructure
batadv_v_ogm_forward")
Reported-by: Sven Eckelmann <sven.eckelmann@open-mesh.com>
