st/mesa: stop using pipe_sampler_view_release()

In all instances here we can replace pipe_sampler_view_release(pipe,
view) with pipe_sampler_view_reference(view, NULL) because the views
in question are private to the state tracker context.  So there's no
danger of freeing a sampler view with the wrong context.

Testing done: google chrome, misc GL demos, games
