Here try to reuse nvme_rdma_teardown_admin_queue() to fix this issue and simplify the code.

NVMe-oF host/target sessions are ordinary network protocol exchanges, matching the treatment of other nvme fabrics host-side flaws.\nAC:L - The target only has to advertise a non-zero icdoff or clear NVME_CTRL_SGLS_KSDBDS to deterministically force the host into the destroy_admin path, and any admin request left undispatched on the quiesced queue makes the freeze wait forever. The attacker can also re-drive controller creation repeatedly via discovery-log-change AENs, so no condition outside their control must happen to line up.\nPR:N - The attacker is the remote peer and needs no credentials on the victim host \u2014 NVMe-oF requires no mandatory authentication, and there is no capable() check anywhere on the nvmf_dev_write \u2192 nvme_rdma_setup_ctrl path. The host-side privileged action is performed by the system\u0027s own autoconnect tooling, not by the attacker.\nUI:N - On hosts configured for NVMe-oF, systemd/udev autoconnect creates controllers (new=true) automatically in response to discovery-log-change AENs from the target, so no human action is needed at exploitation time.\nS:U - The hang is confined to the kernel\u0027s own block/NVMe layer and the calling process; no security authority or isolation boundary is crossed.\nC:N - The defect is a missing unquiesce leading to an indefinite wait in blk_mq_freeze_queue_wait(); no freed or out-of-bounds memory is read and nothing is disclosed to the attacker.\nI:N - There is no memory corruption, no write primitive, and no unintended state modification \u2014 the queue simply never drains, so no data can be altered.\nA:H - The calling task blocks forever in TASK_UNINTERRUPTIBLE and is unkillable, holding nvmf_dev_mutex so every later /dev/nvme-fabrics operation on the system wedges too, pinning the module and preventing clean shutdown; the hung-task watchdog fires and panics the box when hung_task_panic is set."
