[B.A.T.M.A.N.] [PATCH] batman-adv: Fix compilation with linux 2.6.29 and 2.6.30

[Sven Eckelmann <sven@narfation.org>]

Linux v2.6.30-2332-gfddd520 introduced a seventh parameter to
__module_param_call. It is used to give a slightly different user experience
for bool parameters. Older kernels can just drop this information using a
special compat wrapper for __module_param_call.
