Fixes: #95388
#86316 changed the way we store roughness in the normal_roughness buffer. We can't use the buffer value directly. In the SSR shader we calculate the transformed roughness at the top, but we mistakenly continued to read from the non-transformed roughness for calculating the roughness_fade.
