Neil Roberts f84839e87c pipeline-state: Fix crash in the get_all_uniform_values function
The get_all_uniform_values function tries to walk the parent hierarchy
of pipelines to find pipelines overriding the uniforms state and then
grabs the values from the override. However it was accessing data
inside the ‘big state’ even if the pipeline didn't override the
uniforms state so it would crash if it encountered a parent pipeline
with no big state.
