nft: cache: Avoid double free of unrecognized base-chains

On error, nft_cache_add_chain() frees the allocated nft_chain object
along with the nftnl_chain it points at. Fix nftnl_chain_list_cb() to
not free the nftnl_chain again in that case.

Fixes: 176c92c26bfc9 ("nft: Introduce a dedicated base chain array")
