I think that's overkill.  It only needs _bh annotations, not _irqsave/restore
- but even that is probably not the best way.

The best way is to offload the stuff done by rxrpc_rcu_destroy_call() to a
workqueue if called in softirq mode.  I'm not sure whether rcu callbacks are
done in softirq mode - if they are, then it can just call rxrpc_queue_work().
