[B.A.T.M.A.N.] [PATCH 2/2] batman-adv: Backport dev_hw_addr_random

[Sven Eckelmann <sven@narfation.org>]

910ccacb9dd2bfac8ce1ac411af514fe72fa84c0 introduced the hardware address
initialization using dev_hw_addr_random. This function was added to linux with
linux 2.6.36. Older kernel versions have to igore the NET_ADDR_RANDOM variable
and use random_ether_addr directly.
