I don't like the calling convention. We only have have two callers
anyway. So I'd much rather only keep the code inside the if above
in the new nvme_rdma_destroy_admin_queue that is only called at shutdown
time, and opencode the calls to nvme_rdma_stop_queue, nvme_rdma_free_qe
and nvme_rdma_free_queue in the callers.

PCIe is just checking for a non-null admin_q. But I think we should
jsut split this into two functions, one for the shared code at the end
and one just for the first-time setup, with the nvme_rdma_init_queue
call open coded.

Where does this come from?
