st/nine: Fix a crash if the state is not initialized
I don't remember exactly the conditions of the crash,
but I had a trace which was crashing in the gallium driver
before doing any rendering (something about viewports being not initialized).
It's not the first time we hit such a problem, so rather than investigating
that crash, I chose to just initialize every states at device creation.
