> When using multiple queues, there was a race with the kernel
> in setting up the second channel. This regression is due to a kernel change
> which does not allow accessing sysfs files for Hyper-V channels that are not opened.
>
> The fix is simple, just move the logic to detect not ready
> sub channels earlier in the existing loop.
