#490 memory leak in WriteFITSImage

[bestshow]

Here is the critical code : (in WriteFITSImage)

  fits_info=MagickAllocateMemory(char *,FITS_BLOCK_SIZE);
  pixels=MagickAllocateMemory(unsigned char *,packet_size*image->columns); //768
  if ((fits_info == (char *) NULL) || (pixels == (unsigned char *) NULL))
    {
      MagickFreeMemory(fits_info);
      ThrowWriterException(ResourceLimitError,MemoryAllocationFailed,image);
    }

If "fits_info" is null and the "pixels" was not null,the pixels will cause meomory leak.
