nvmet-rdma: update queue list during ib_device removal
A NULL deref happens when nvmet_rdma_remove_one() is called more than once (e.g. while connected via 2 ports). The first call frees the queues related to the first ib_device but doesn't remove them from the queue list. While calling nvmet_rdma_remove_one() for the second ib_device it goes over the full queue list again and we get the NULL deref.
