staging: wlan-ng: Use net_device_stats from struct net_device
Instead of using an own copy of struct net_device_stats in struct
wlandevice, use stats from struct net_device. Also remove the thus
unnecessary .ndo_get_stats function, as it would now just return
netdev->stats, which is the default in dev_get_stats().
Furthermore, convert prefix increment of stats counters to the more
common postfix increment idiom.
