Subject: batman: fix a bogus warning from batadv_is_on_batman_iface()
From: Cong Wang <cwang@xxxxxxxxxxxxxxxx>
commit b6ed5498601df40489606dbc14a9c7011c16630b upstream.
batman tries to search dev->iflink to check if it's a batman interface,
but ->iflink could be 0, which is not a valid ifindex. It should just
avoid iflink == 0 case.
