[ Upstream commit 91c11d5f32547a08d462934246488fe72f3d44c3 ]
when starting error recovery there might be a authentication work running, and it involves I/O commands. Given the controller is tearing down there is no chance for the I/O to complete other than timing out which may unnecessarily take a full io timeout.
So first tear down the queues, fail/cancel all inflight I/O (including potentially authentication) and only then stop authentication. This ensures that failover is not stalled due to blocked authentication I/O.
