netfilter: nft_flow_offload: reset dst in route object after setting up flow

Browse source

[ Upstream commit 9e0f043038 ]

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.
