RDMA/devices: Remove the lock around remove_client_context
Due to the complexity of client->remove() callbacks it is desirable to not hold any locks while calling them. Remove the last one by tracking only the highest client ID and running backwards from there over the xarray. Since the only purpose of that lock was to protect the linked list, we can drop the lock.
