[Mesa-stable] [PATCH 1/5] i965: Always intel_prepare_render() after invalidating front buffers.

Fixes glean/texture_srgb, which hit recursive-flush prevention
assertions in vbo_exec_FlushVertices.

This probably hurts the performance of front buffer rendering, but
very few people in their right mind do front buffer rendering.

Fixes Glean's texture_srgb test.
