tun: switch to net core provided statistics counters

Switch tun to the standard statistics pattern:
- use netdev->stats for the less frequently accessed counters
- use netdev->tstats for the frequently accessed per-cpu counters

v3:
- add atomic_long_t member rx_frame_errors for making counter updates
  atomic
