This stems from a time when sets and nft_dynset resided in different kernel
modules. We can replace this with a direct call.
We could even remove both ->update and ->delete, given its only
supported by rhashtable, but on the off-chance we'll see runtime
add/delete for other types or a new set type keep that as-is for now.
