Subject: [PATCH net-next 06/11] net: gianfar: use devm_alloc_etherdev_mqs

There seems to be a mistake here. There's a num_rx_qs variable that is not
being passed to the allocation function. The mq variant just calls mqs
with the last parameter of the former duplicated to the last parameter
of the latter. That's fine if they match. Not sure they do.

Also avoids manual free_netdev
