Proof of bug script

System:
Gentoo AMD64, kernel 4.8.1
nft, libmnl, libnftnl compiled from git (as of 13.10.2016)

When adding IPv4 addresses one by one to set { type ipv4_addr; flags interval;
}, then deleting them all in one command, then adding them one by one again to
emptied set, some IPv4 addresses are shown as already in set, but they are not.

Without flags interval everything is ok. Or when deleting IPv4 addresses one by
one too, everything is ok.

It looks like some inconsistency in interval handling when deleting multiple
items in one command.

Example shell script is attached.</pre>
