nft: fix wrong function to release iterator

nft.c: In function ‘nft_xtables_config_load’:
nft.c:2522:3: warning: passing argument 1 of ‘nft_table_list_iter_destroy’ from incompatible pointer type [enabled by default]
In file included from nft.c:41:0:
/usr/include/libnftables/table.h:64:6: note: expected ‘struct nft_table_list_iter *’ but argument is of type ‘struct nft_chain_list_iter *’

Introduced in (12eb85b nft: fix memory leaks in
nft_xtables_config_load) but that was my fault indeed since Ana sent
a v2 patch that I have overlook.
