[PATCH net 1/2] net: ntb_netdev: Avoid double-accounting netif_rx() drops

netif_rx() already accounts packets it drops in the core rx_dropped
counter. ntb_netdev counts them again as both errors and drops.
Leave netif_rx() drops to the core. Count the packet and bytes
unconditionally since it was received successfully by the driver.
Fixes: 548c237c0a99 ("net: Add support for NTB virtual ethernet device")
