svga: set rendered_to flag with texture uploaded using TransferFromBuffer command

This patch sets the rendered_to flag for the texture subresource that
is uploaded using the TransferFromBuffer command. This is to ensure that
the subresource will be read back or invalidated before it will be
directly mapped to. This makes sure that the content of the GB surface
will not be accidentally overwritten by the device at suspend/resume time.
