The admin queue is hardly ever used (if at all) compared to an IO queue's
usage, so why waste the resource? I bet you can't measure a preformance
difference on queues that don't share, and it's reasonable to expect an
nvme controller's MSI-x count matches the IO queue count, which forces
us to share a vector.
