[RFC v3 1/4] batman-adv: Let packet.h include its headers directly

The headers used by packet.h should also be included by it directly. main.h is currently dealing with it in batman-adv, but this will no longer work when this header is moved to include/uapi/linux/. Signed-off-by: Sven Eckelmann --- net/batman-adv/main.h | 2 --
