The nvme multipath error handling defaults to controller reset if the error is unknown. There are, however, no existing nvme status codes that indicate a reset should be used, and resetting causes unnecessary disruption to the rest of IO. Change nvme's error handling to first check if failover should happen. If not, let the normal error handling take over rather than reset the controller.
