i965: do not emit empty surface state
If called with an empty size, brw_emit_buffer_surface_state asserts. We already have a dedicated helper for uploading nothing, so let's use that instead. Avoids an assert in dEQP-GLES31.functional.shaders.opaque_type_indexing.ssbo.const_literal_vertex when running a debug build of i965.
