avcodec/magicyuv: Don't invert order unnecessarily
The MagicYUV decoder currently sets both the length and the symbol field of an array of HuffEntries; hereby the symbol of the ith entry (0-based) is just i. Then said array gets sorted so that entries with greater length are at the end and entries with the same length are ordered so that those with smaller symbols are at the end. Afterwards the newly sorted array is traversed in reverse order. This commit instead inverts the ordering and traverses the array in its ordinary order in order to simplify understanding.
