llvmpipe: Cope with null Vertex element cso.
CSO can often be null. For example: 1. at initialization 2. using an util module (u_blit) right after initialization (it will push state and pop the previous null state) 3. at shutdown time (state shouldn't be bound when being destroyed) Glean was hitting 2.
