[B.A.T.M.A.N.] [PATCH] batman-adv: fix compat of net_ratelimited_function for >3.2.46

[Simon Wunderlich]

From: Simon Wunderlich <si...@open-mesh.com>

Appearently net_ratelimited_function was added to the stable series of
from 3.2.47, which results in a lot of warnings when compiling against
this kernel. This patch avoids this redefinition.
