ipv4: Fix route refcount on pmtu discovery
[ Upstream commit b44108dbdbaa07c609bb5755e8dd6c2035236251 ] git commit 9cb3a50c (ipv4: Invalidate the socket cached route on pmtu events if possible) introduced a refcount problem. We don't get a refcount on the route if we get it from__sk_dst_get(), but we need one if we want to reuse this route because __sk_dst_set() releases the refcount of the old route. This patch adds proper refcount handling for that case. We introduce a 'new' flag to indicate that we are going to use a new route and we release the old route only if we replace it by a new one.
