Sami Boukortt 3ec225dd41 Fix a memory leak in png_set_tRNS ...

This leak was discovered by OSS-Fuzz.

The old structure of the code was along the lines of:

  allocate trans_alpha;
  if (problem) {
    // Jumps away from this function
    png_warning("tRNS chunk has out-of-range samples for bit_depth");
  }
  mark trans_alpha as to-free;
