ab22a71429f0f47b3c3582a303c07940aa59cd3e refactor: cast bool to int to silence compiler warning (Jon Atack)

Pull request description:

  This fixes a compiler warning:
  ```
  node/interfaces.cpp:544:16: warning: use of bitwise '&' with boolean operands [-Wbitwise-instead-of-logical]
          return FillBlock(ancestor, ancestor_out, lock, active) & FillBlock(block1, block1_out, lock, active) & FillBlock(block2, block2_out, lock, active);
