anv: fix 3DSTATE_MULTISAMPLE emission on gen8+

Browse source 
When pipeline->dynamic_state.sample_locations.samples is not set
because the state is dynamic, we're currently calling
genX(emit_multisample) with a 0 samples value which is incorrect.

Found when using renderdoc with the drawing overlay.
