skbuff: Release nfct refcount on napi stolen or re-used skbs
commit 8550ff8d upstream. When multiple SKBs are merged to a new skb under napi GRO, or SKB is re-used by napi, if nfct was set for them in the driver, it will not be released while freeing their stolen head state or on re-use. Release nfct on napi's stolen or re-used SKBs, and in gro_list_prepare, check conntrack metadata diff.
