glsl/ast: update rhs in addition to the var's constant_value
We continue in the code to do some more things with the rhs, including setting a constant initializer. If the type is wrong, this causes some confusion down the line, leading to assertions. This makes sure that the rhs processing continues to flow as-if the type was correct to start with (even though the state has been marked as an error state).
