[Nouveau] [PATCH] nouveau/video: make sure that firmware is present when checking caps

Apparently some players are ill-prepared for us claiming that a decoder
exists only to have creating it fail, and express this poor preparation
with crashes (e.g. flash). Check that firmware is there to increase the
chances of there being a high correlation between reported capabilities
and ability to create a decoder.

I tested this on a VP3 card. Would be nice if someone could give the (somewhat
different) vp2 logic a shot. Emil perhaps? If no one confirms after a while
I'll go swap cards in my computer.
