[PATCHv2-4.5 09/10] NVMe: Mark queues as dead on degraded controller

[Keith Busch]

If a previously optimal controller goes degraded, the IO queues will
stop working, but the controller is still managable. Prior to removing
namespace, we need to fail the queues so queued and new IO will fail
and allow namespace removal to progress.
