Alexandre Belloni fec9d3b1dc net: macb: initialize bp->queues[0].bp for at91rm9200
The macb driver currently crashes on at91rm9200 with the following trace:

Unable to handle kernel NULL pointer dereference at virtual address 00000014

Solve that by initializing bp->queues[0].bp in at91ether_init (as is done
in macb_init).
