Shuhei Matsumoto 3182be6d26 bdev/nvme: Fail fast I/O qpair if poll_group_process_completions() returns negated errno ... If qpair is disconnected asynchronously, it takes time from detecting transport error to actually disconnected. We should avoid using the path as soon as possible after detecting any transport error. Poll group clears I/O path cache if it finds transport error and avoid using the path which had transport error. These changes will reduce the failover time.
