[B.A.T.M.A.N.] [PATCHv3 3/3] batman-adv: use static inline functions to fake not compiled-in routines

[Antonio Quartulli <ordex@autistici.org>]

In case of not compiled-in components, we need to fake some functions in order
to let the rest of the code correctly build. But instead of using something
like:

We have to use:

static inline bla_init(struct bat_priv *bat_priv)
{
	return 1;
}

In this way the compiler can correctly check the type and the number of the
arguments passed to the function, even if the related component (bla in this
case) is not compiled.
