netlink: Avoid crash with clientless netlink

In some pathological configurations, it can happen that a packet is
received from the kernel by a netlink which has no clients (that is,
where netlink_inst_reg has not been called).

Don't crash when this happens; instead, print a log message including
the source and destination addresses.
