gallium: fix some surface usage bugs
When a surface is created with GPU_WRITE that really means "GPU render"
and that can involve reads (blending). Set surface usage to
PIPE_BUFFER_USAGE_CPU_READ + WRITE. Fixes progs/demos/lodbias demo.
Also, mark texture as 'modified' when mapped for writing so that the tile
cache can know when to freshen a cached tile. Fixes glTexSubImage2D().
