netfilter: ebtables: make broute table work again

Browse Source 
broute table init hook sets up the "br_should_route_hook" pointer,
which then gets called from br_input.

commit a386f99025
(bridge: add proper RCU annotation to should_route_hook)
introduced a typedef, and then changed this to:

br_should_route_hook_t *rhook;
[..]
rhook = rcu_dereference(br_should_route_hook);
if (*rhook(skb))

problem is that "br_should_route_hook" contains the address of the function,
so calling *rhook() results in kernel panic.
