decoder: fix reinit when Huffman is run on CPU

broken by the commit 41fb824 (15th Jan 2025)

The problem is after that change when using CPU Huffman decoder,
and using the 2nd image smaller than the first that since
the commit, the per-component pointers won't get updated by
gpujpeg_coder_allocate_cpu_huffman_buf(), which is no longer called
(data_quantizied != NULL).

fixes <#108>
