How is ->remove_port synchronized vs the RDMA/CM even handler?

Easy, it isn't :)

So we have three choices here:
1. Add a lock in nvmet_port that only rdma will use for now (don't like
it)
or
2. Add nvmet_rdma_port as nvmet_port->priv with a lock (don't like it)
or
3. take the global nvmet_config_sem (hate it)

Any preferences?

(4) use cmpxchg?
