mesa: set _NEW_BUFFERS when updating texture bound to current buffers 

When a glTexImage call updates the parameters of a currently bound
framebuffer, we might miss out on revalidating whether it is complete.
Make sure to set _NEW_BUFFERS which will trigger the revalidation in
that case.

Also while we're at it, fix the fb parameter passed in to the eventual
RenderTexture call.
