Add polling timeout.

Polling now has a timeout to abort.

If it fails in the for loop from ringSetup, it aborts the complete loop for that specific ring so that it doesn't try again two times in a row.

  const auto nodes = topology_.getNodesForRing(ring);
  for (const auto &node : nodes) {
    stat = nodeSetup(ring, node.first);
    if (node.first == nodes.rbegin()->first) {
      if (stat == rmmSuccess) finalRingSetup(ring, node.first);
    } else {
      RMMRegs.feaFwRegWrite("RVSR_SLV", ring, node.first, 0x0, "S");
    }
  }
