net: bcmgenet: correct per TX/RX ring statistics

Browse source 
[ Upstream commit a6d0b83f25 ]

The change to track net_device_stats per ring to better support SMP
missed updating the rx_dropped member.

The ndo_get_stats method is also needed to combine the results for
ethtool statistics (-S) before filling in the ethtool structure.
