Part of the nvme recovery process for errors is to reset the card. Sometimes, this results in failing the entire controller. When nda is in use, we free the sim, which will sleep until all the I/O has completed. However, with only one thread, the request fail task never runs once the reset thread sleeps here. Create two threads to allow I/O to fail until it's all processed and the reset task can proceed. This is a temporary kludge until I can work out questions that arose during the review, not least is what was the race that queueing to a failure task solved. The original commit is vague and other error paths in the same context do a direct failure. I'll investigate that more completely before committing changing that to a direct failure. mav@ raised this issue during the review, but didn't otherwise object. Multiple threads, though, solve the problem in the mean time until other such means can be perfected.
