st/mesa: Unreference the sampler view in st_bind_surface.

Without this, update_textures may not pick up the new pipe_resource.

It is actually update_textures that should check
stObj->sampler_view->texture != stObj->pt, but let's follow st_TexImage
and others for now.
(cherry picked from commit cfc81d93f7b07a89437cbbce173fc468070e06da)
