Kees Cook dc5306a8c0 decnet: Use container_of() for struct dn_neigh casts
Clang's structure layout randomization feature gets upset when it sees
struct neighbor (which is randomized) cast to struct dn_neigh:

net/decnet/dn_route.c:1123:15: error: casting from randomized structure pointer type 'struct neighbour *' to 'struct dn_neigh *'
			gateway = ((struct dn_neigh *)neigh)->addr;
				   ^

Update all the open-coded casts to use container_of() to do the conversion
instead of depending on strict member ordering.
