Fixed multiprocessor sharpening bug

Question

Originally reported on Google Code with ID 1454

While searching the sharpening code for another bug, I found this one.

The bug does not show up often, since on my setup OpenMP decides only to use one core,
but it may show up on other setups.

Nice side effect is that we have a multithreaded aligned buffer now that also improves
ICC transformationes for monitor etc. by a few percent.

Thanks Olli, I can try to test this, but I am on 12 threads CPU now (48GHz total) and
RT flies even on D800E files:) Performance difference (although super-appreciated!)
 would be hard to detect visually in my setup. Should I pay attention to anything specific?
