Do not trigger a KASSERT() when destroying/detaching an interface with

RTF_CLONED routes attached.

In thise case if_get(9) can return NULL inside rtflushclone1() because
ifdetach() starts by clearing the interface pointer in the index map.

So it is perfectly correct to bail and we're not going to leak any route
entry because we're garbage collecting all of them.
