dco-linux: fix counter print format

Avoid compilation warnings on 32 bit platforms.

dco_linux.c: In function 'dco_update_peer_stat':
dco_linux.c:830:26: error: format '%lu' expects argument of type
'long unsigned int', but argument 4 has type 'counter_type'
{aka 'long long unsigned int'} [-Werror=format=]
  830 |         msg(D_DCO_DEBUG, "%s / dco_read_bytes: %lu", __func__,
      |                          ^~~~~~~~~~~~~~~~~~~~~~~~~~
  831 |             c2->dco_read_bytes);
      |             ~~~~~~~~~~~~~~~~~~

      |               counter_type {aka long long unsigned int}
