gianfar: Fix stats support
This patch updates the per rx/tx queue stats.
To update the per rx queue stats a new structure has been
introduced rx_q_stats.
The per tx queue stats are updated via the netdev_queue
structure itself.
Note that we update only the tx_packtes, tx_bytes, rx_packets,
rx_bytes and rx_dropped stats on a per queue basis.
