Commit d6e0b7fa ("slub: make dead caches discard free slabs
immediately") makes put_cpu_partial() run with preemption disabled and
interrupts disabled when calling unfreeze_partials().

The comment: "put_cpu_partial() is done without interrupts disabled and
without preemption disabled" looks obsolete, so remove it.
