netfilter: nf_tables: disallow element updates of bound anonymous sets

[ Upstream commit c88c535b592d3baeee74009f3eceeeaf0fdd5e1b ]

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.
