Fixed bug 2098 - Pointer variable not initialized in IMG_SavePNG_RW()

manuel.montezelo In line 618 of http://hg.libsdl.org/SDL_image/file/361ab0371a02/IMG_png.c void *png; it's not initialized to =NULL, and possibly can be used without being initialized (or otherwise, the nearby check "if (png)" doesn't make much sense, I think).
