netfilter: nf_tables: disallow element updates of bound anonymous sets

Browse source

[ Upstream commit c88c535b59 ]

Anonymous sets come with NFT_SET_CONSTANT from userspace. Although API
allows to create anonymous sets without NFT_SET_CONSTANT, it makes no
sense to allow to add and to delete elements for bound anonymous sets.
