[B.A.T.M.A.N.] [PATCH 8/9] Staging: batman-adv: convert vis_interval into define

[Sven Eckelmann <sven.eckelmann@gmx.de>]

From: Simon Wunderlich <siwu@hrz.tu-chemnitz.de>

vis_interval does not neccesarily needs to be a variable, as there is
no way to change it anyway (and probably no need to). We can therefore
remove yet another global variable.

Thanks Marek for pointing this out.
