Subject: [PATCH net 02/17] netfilter: nf_tables: disallow NFTA_SET_ELEM_KEY_END with NFT_SET_ELEM_INTERVAL_END flag

From: Pablo Neira Ayuso <pablo@...filter.org>

These are mutually exclusive, actually NFTA_SET_ELEM_KEY_END replaces
the flag notation.

Fixes: 7b225d0b5c6d ("netfilter: nf_tables: add NFTA_SET_ELEM_KEY_END attribute")
