cso: Don't restore nr_samplers in cso_restore_fragment_samplers
If info->nr_samplers > ctx->nr_fragment_samplers_saved, the assignment
would prevent cso_single_sampler_done from unbinding the no longer used
samplers from the driver, which could result in use-after-free. This is
probably unlikely to happen in practice though.
