netfilter: nft_set_pipapo: release elements in clone only from destroy path
Clone already always provides a current view of the lookup table, use it
to destroy the set, otherwise it is possible to destroy elements twice.
This fix requires:
212ed75dc5fb ("netfilter: nf_tables: integrate pipapo into commit protocol")
which came after:
9827a0e6e23b ("netfilter: nft_set_pipapo: release elements in clone from abort path").
Fixes: 9827a0e6e23b ("netfilter: nft_set_pipapo: release elements in clone from abort path")
