[B.A.T.M.A.N.] [PATCH 06/16] batman-adv: tvlv realloc, move error handling into if block

[Antonio Quartulli <antonio@meshcoding.com>]

From: Markus Pargmann <mpa@pengutronix.de>

Instead of hiding the normal function flow inside an if block, we should
just put the error handling into the if block.
