Use the core_stats rx_dropped counter to avoid the cost of atomic
increments.

Signed-off-by: Guillaume Nault <gnault@redhat.com>

I'm using core_stats for consistency with the vxlan implementation.
If we really want to avoid using core_stats in tunnel drivers, just
let me know and I'll convert bareudp to NETDEV_PCPU_STAT_DSTATS. But
for the moment, I still prefer to favor code consistency across UDP
tunnel implementations.
