netfilter: nf_tables: tighten netlink attribute requirements for catch-all elements

[ Upstream commit d4eb7e39929a3b1ff30fb751b4859fc2410702a0 ]

If NFT_SET_ELEM_CATCHALL is set on, then userspace provides no set element
key. Otherwise, bail out with -EINVAL.

Fixes: aaa31047a6d2 ("netfilter: nftables: add catch-all set element support")
