vdpau: always render to cropped size at most

Browse Source 
vo_opengl (or gl_hwdec_vdpau.c to be specific) calls
mp_vdpau_mixer_render() with video_rect=NULL, which means to use the
full surface. This is incorrect if the surface is actually cropped, as
it can happen with h264. In this case, it was rendering the parts
outside of the image.

Fix it by making this case use the cropped size instead.

Alternative fix for PR #1863.
