Fix out of bound memory access in lppTransposer

In TRANSPOSER_SETTINGS, initialize the whole bwBorders array to a
  reasonable value to guarantee correct termination in while loop
  in lppTransposer function. This fixes the reported bug.
For completeness:
  - clear the whole bwIndex array instead of noOfPatches entries only.
  - abort criterion in while loop to prevent potential
    infinite loop, and limit bwIndex[patch] to a valid range.
