    netfilter: nft_immediate: drop chain reference counter on error
    
    [ Upstream commit b29be0ca8e816119ccdf95cc7d7c7be9bde005f1 ]
    
    In the init path, nft_data_init() bumps the chain reference counter,
    decrement it on error by following the error path which calls
    nft_data_release() to restore it.
