ipv4: Kill rt->rt_oif
Never actually used. It was being set on output routes to the original OIF specified in the flow key used for the lookup. Adjust the only user, ipmr_rt_fib_lookup(), for greater correctness of the flowi4_oif and flowi4_iif values, thanks to feedback from Julian Anastasov. Signed-off-by: David S. Miller <davem@davemloft.net>
