Subject: netfilter: nf_tables: revert do not remove elements if set backend implements .abort

From: Pablo Neira Ayuso <pablo@xxxxxxxxxxxxx>

commit f86fb94011aeb3b26337fc22204ca726aeb8bc24 upstream.

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.
