svga: invalidate gb surface before it is reused
With this patch, a guest-backed surface will be invalidated using the SVGA_3D_CMD_INVALIDATE_GB_SURFACE command before the surface is reused. This fixes the updating dirty image error from the device when a surface is reused. v2: Instead of invalidating the surface when it is reused, send the invalidate command before the surface is put into the recycle pool. v3: (1) surface invalidate is a noop operation in Linux winsys, since surface invalidation is not needed for DMA path. (2) Instead of invalidating the surface content in svga_screen_surface_destroy() when a surface is to be destroyed, it is done in svga_screen_cache_flush() when the surface is no longer referenced in a command buffer and is ready to be moved to the unused list. At this point, the surface will be moved to the invalidate list. When the surface invalidation is submitted, the surface will be moved to the unused list. Tested with piglit, glretrace.
