radeon: avoid segfault when pixmap exceed GPU capabilities
We might get a request for a pixmap/drawable that is too big
for GPU capabilities in the dri2 get buffer path. In face of
such things just return NULL to dri2 get buffer request. The
GL driver should then use something like transparent black to
avoid something too ugly on the screen.
