usbnet: pegasus: Use net_device_stats from struct net_devicends-private-remove
Instead of using a private copy of struct net_device_stats in struct pegasus, use stats from struct net_device. Also remove the now unnecessary .ndo_get_stats function. Cc: Petko Manolov <petkan@nucleusys.com> Cc: linux-usb@vger.kernel.org Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
