From: Pablo Neira Ayuso <pablo@xxxxxxxxxxxxx>
nf_tables_abort_release() path calls nft_set_elem_destroy() for
NFT_MSG_NEWSETELEM which releases the element, however, a reference to
the element still remains in the working copy.
Fixes: ebd032fa8818 ("netfilter: nf_tables: do not remove elements if set backend implements .abort")
