[DECNET]: Convert decnet route to use the new dst_entry 'next' pointer
This patch removes the next pointer from 'struct dn_route.u' union, and renames u.rt_next to u.dst.dn_next. It also moves 'struct flowi' right after 'struct dst_entry' to prepare speedup lookups. Signed-off-by: Eric Dumazet <dada1@cosmosbay.com> Signed-off-by: David S. Miller <davem@davemloft.net>
