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.
