Subject: [PATCH net v5 4/6] Revert "net/ipv6: Bail early if user only wants cloned entries"

This reverts commit 08e814c9e8eb5a982cbd1e8f6bd255d97c51026f: as we
are preparing to fix listing and dumping of IPv6 cached routes, we
need to allow RTM_F_CLONED as a flag to match routes against while
dumping them.
