ipv4: Fix peer validation on cached lookup.
If ipv4_valdiate_peer() fails during a cached entry lookup,
we'll NULL derer since the loop iterator assumes rth is not
NULL.
Letting this be handled as a failure is just bogus, so just make it
not fail. If we have trouble getting a non-NULL neighbour for the
redirected gateway, just restore the original gateway and continue.
The very next use of this cached route will try again.
