netfilter: nft_flow_offload: reset dst in route object after setting up flow
[ Upstream commit 9e0f0430 ] dst is transferred to the flow object, route object does not own it anymore. Reset dst in route object, otherwise if flow_offload_add() fails, error path releases dst twice, leading to a refcount underflow.
