[B.A.T.M.A.N.] [PATCH 03/38] batctl: Drop legacy vis_* related warning messages

[Sven Eckelmann <sven@narfation.org>]

The vis support code was removed with batman-adv 2014.0.0 (Linux 3.13). All
kernel versions with up to this version are EOL for a while and also batctl
warned now about this problem for nearly 5 years. It should therefore no
(serious) problem to remove these warning messages.
