svga: set rendered-to flag after updating the texture using PredCopyRegion

This patch sets the rendered-to flag for the subresource after it is
updated using the PredCopyRegion command. This is to ensure that the GB surface
will be sync up properly before it will be directly mapped to.

Tested with MTT piglit, glretrace.
