    screen: Don't ref workspace->screen after freeing workspace
    
    In meta_screen_remove_workspace its possible that the workspace will be
    disposed before we call meta_screen_set_active_workspace_hint to update
    the active workspace index so we make sure to use the screen pointer
    passed as an argument to meta_screen_remove_workspace() instead of
    referring to the workspace->screen pointer which might cause a crash if
    workspace was indeed freed.
