[BRIDGE]: Properly dereference the br_should_route_hook

This hook is protected with the RCU, so simple

if (br_should_route_hook)
br_should_route_hook(...)

is not enough on some architectures.

Use the rcu_dereference/rcu_assign_pointer in this case.

Fixed Stephen's comment concerning using the typeof().
