[PATCH blktests v1 03/18] nvme/rc: log error if stale configuration is found

[Daniel Wagner]

It's possible that a previous run of blktest left some stale
configuration left. E.g. when the module unload doesn't work (the bug
might in the kernel we are testing). In this case error out and avoid
confusion.
