[PATCH 08/14] netfilter: nf_tables: destroy the set if fail to add transaction

From: Liping Zhang <redacted>

When the memory is exhausted, then we will fail to add the NFT_MSG_NEWSET
transaction. In such case, we should destroy the set before we free it.

Fixes: 958bee14d071 ("netfilter: nf_tables: use new transaction infrastructure to handle sets")
