batman-adv: Calculate sizeof using variable insead of types
Documentation/CodingStyle recommends to use the form p = kmalloc(sizeof(*p), ...); to calculate the size of a struct and not the version where the struct name is spelled out to prevent bugs when the type of p changes. This also seems appropriate for manipulation of buffers when they are directly associated with p. Signed-off-by: Sven Eckelmann <sven@narfation.org>
