get_shell_surface() returns NULL, if the client has not created or has destroyed the wl_shell_surface object. All but one use of get_shell_surface() just retrieve the surface type, so just fall back to SHELL_SURFACE_NORMAL there. Resize hot-key binding really needs the wl_shell_surface object, as that is the only way to send configure events. For surfaces without a wl_shell_surface, simply do not resize them.
