netfilter: nf_tables: release objects on netns destruction
We have to release the existing objects on netns removal otherwise we leak them. Chains are unregistered in first place to make sure no packets are walking on our rules and sets anymore. The object release happens by when we unregister the family via nft_release_afinfo() which is called from nft_unregister_afinfo() from the corresponding __net_exit path in every family.
