drivers: lustre: obdclass: simplify unregister_shrinker() usage

lu_global_fini() explicitly uses knowledge about shrinker's
internals to make decision about calling of unregister_shrinker().
Now this check was integrated into unregister_shrinker(),
so it is safe to call it against unregistered shrinker.
