ip_tunnel: fix preempt warning in ip tunnel creation/updating
After the commit e09acddf873b ("ip_tunnel: replace dst_cache with generic implementation"), a preemption debug warning is triggered on ip4 tunnels updating; the dst cache helper needs to be invoked in unpreemptible context. We don't need to load the cache on tunnel update, so this commit fixes the warning replacing the load with a dst cache reset, which is preempt safe.
