Modify polartest, smallblocktest and ldpctest to return '0' on success

- Updated polartest, smallblocktest, and ldpctest to check BLER and return
  appropriate status:
  - Returns '0' if BLER equals 0.000000 (indicating success).
  - Returns '1' for all other BLER values (indicating failure).
- This change improves consistency in return values across the test physims.
