[IPV4]: Fix refcount damaging in net/ipv4/route.c
One such place that can damage the dst refcnts is route.c with CONFIG_IP_ROUTE_MULTIPATH_CACHED enabled, i don't see the user's .config. In this new code i see that rt_intern_hash is called before dst->refcnt is set to 1, dst is the 2nd arg to rt_intern_hash. Arg 2 of rt_intern_hash must come with refcnt 1 as it is added to table or dropped depending on error/add/update. One such example is ip_mkroute_input where __mkroute_input return rth with refcnt 0 which is provided to rt_intern_hash. ip_mkroute_output looks like a 2nd such place. Appending untested patch for comments and review. The idea is to put previous reference as we are going to return next result/error.
