Fix a segfault that occured in the MIPS DSPr2 fancy upsampling routine when downsampled_width==3.  Because the DSPr2 code unrolls the loop for the middle columns (refer to jdsample.c), it has the effect of performing two column iterations, and that only works properly if the number of columns (minus the first and last) is >= 2.  For the specific case of downsampled_width==3, this patch skips to the second iteration of the unrolled column loop.
