svga: increment texture age when surface is to be marked as dirty
Commit b9ba8492 removes an unneeded pipe_surface_release() from
st_render_texture(). This implies a surface can now be reused for a
render buffer. Currently, when we render to a texture, we mark the
surface as dirty. But in svga_mark_surface_dirty(), if the surface
is already marked as dirty, it does not increment the texture age.
Any view to this texture might not be updated properly then.
With this patch, the texture age is incremented regardless of whether
the surface is already marked as dirty or not.
Fix bug 1499181.
