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.
