Back to the drawing board, I'll drop the series. Still off from work
here, I'll take a look when I get back soon. I'm surprised it's this
difficult, we already went through most of this design/test hash out

I'll drop this one:
NVMe: Freeze queues on shutdown
but keep this one:
NVMe: Fix double free irq
Agree?
