[B.A.T.M.A.N.] [PATCH] batman-adv: fix logic error in batadv_v_ogm_forward

[Simon Wunderlich]

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")
