[B.A.T.M.A.N.] [PATCH 08/12] batman-adv: Remove unnecessary check for orig_ifinfo not NULL

From: Sven Eckelmann <sven@narfation.org>

orig_ifinfo is dereferenced multiple times in batadv_iv_ogm_update_seqnos
before the check for NULL is done. The function also exists at the
beginning when orig_ifinfo would have been NULL. This makes the check at
the end unnecessary and only confuses the reader/code analyzers.
