gianfar: Fix gianfar select_queue bogosity

The gfar_select_queue() function was used to set queue mapping
only for forwarding/bridging applications and the condition
for locally generated packets was completely ignored.

The solution is to remove the gfar_select_queue() function and
use skb_record_rx_queue to set queue mapping for
forwarding/bridging applications. This will ensure that in case of
forwarding/bridging applications txq = rxq will be selected and
skb_tx_hash will be used to pick up a txq for locally generated packets.
