h264: vdpau: fix crash with unsupported colorspace 

The h264_vdpau decoder crashed if output colorspace was not 8-bit 420.
Add a check to error out instead (current hardware does not support
other colorspaces, so successful decoding is not possible).

Check implemented at a different place by michael, thus blame for bugs goes to michael
