Fix LeDevice, ClassicDevice, Device, AdapterConfig less than operators

If a class has two members A and B, and we want to order the class by A
first and then by B:
  obj1.A < obj2.A && obj1.B < obj2.B
is the wrong alrogithm. Instead, something like
  if (obj1.A != obj1.A) {
    return obj1.A < obj2.A;
  }
  return obj1.B < obj2.B;
should be used.

An incorrectly implemented less than operator will affect std::map's
functionality as std::map thinks that
  if (!(obj1 < obj2) && !(obj2 < obj1)) ==> obj1 == obj2
