NET: hamradio: Fix IP over bpq encapsulation.

Since 1d5da757da860a6916adbf68b09e868062b4b3b8 (ax25: Stop using magic neighbour cache operations.) any attempt to transmit IP packets over a bpqether device will result in a message like "Dead loop on virtual device bpq0, fix it urgently!"

Fix suggested by Eric W. Biederman <[email protected]>.
