Subject: [PATCH net-next 16/21] veth: rename drop xdp_ suffix from packets and bytes stats

They get updated not only on XDP path. Moreover, packet counter
stores the total number of frames, not only the ones passed to
bpf_prog_run_xdp(), so it's rather confusing.
Drop the xdp_ suffix from both of them to not mix XDP-only stats
with the general ones.
