When the fuzzer runs, the system does not notice that something goes
wrong until rose_find_listener() returns NULL in rose_rx_call_request
whereas Bernard's connect passes this test.

Testing both sk == NULL and !neigh->dev after rose_find_listener may
work but it looks like an ugly bandaid.

Good night.
