Fixed bug 5146 - SDL_RenderFillRect doesn't work in DirectFB

Lacky

It looks like refactoring of SDL2 internal API has broken SDL_RenderFillRect for DirectFB. In new version function SDL_RenderFillRect returns 0, but rectangle is not visible.

Replacing "count" with "len" in the argument list for SDL_memcpy in DirectFB_QueueFillRects fixes problem.
