SSE2 SIMD: Fix prog Huffman enc. error if Sl%16==0

(regression introduced by 5b177b3cab5cfb661256c1e74df160158ec6c34e)

The SSE2 implementation of progressive Huffman encoding performed
extraneous iterations when the scan length was a multiple of 16.

Based on:
https://github.com/rouault/libjpeg-turbo/commit/bb7f1ef98305da915e581b59bd0ec2ef7bdb8468

Fixes #335
Closes #367
