ipv4: Cache ip_error() routes even when not forwarding.
And account for the fact that, when we are not forwarding, we should bump statistic counters rather than emit an ICMP response. RP-filter rejected lookups are still not cached. Since -EHOSTUNREACH and -ENETUNREACH can now no longer be seen in ip_rcv_finish(), remove those checks. Signed-off-by: David S. Miller <davem@davemloft.net>
