[PATCH] nvmet-rdma: removed queues cleanup from module exit

[sagi@grimberg.me (Sagi Grimberg)]

We already do that when we are notified in device removal
which is triggered when unregistering as an ib client.

Signed-off-by: Sagi Grimberg <sagi at grimberg.me>

Changes from v1:
- warn if list is not empty after we unregistered the ib_client (which
  is a definite memory leak)
