libhb: Minor nlmeans optimizations.

Use calloc for nlmeans integral instead of memsets in-loop zeroing.
Replace superfluous const with literal in SSE implementation.
Move exponential table calculation out of the main loop.
More const correctness.
Add some braces.

Overall, slightly more readable/maintainable and (very) slightly faster.
