netfilter: nft_immediate: drop chain reference counter on error

Browse Source 
[ 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.
