annotate src/video/x11/SDL_x11dyn.c @ 3958:85b6fb6a5e3c SDL-1.2

Actually, this is a better fix...clear the error state once if everything we need loaded; it's more efficient, and works even if the last unnecessary xrandr symbol failed to load. Otherwise, leave the original loadso error, so the end user can find out what symbol failed.
