This patch creates an emulated device which helps to test and debug the
kernel driver for iopmem while hardware availability is poor. A kernel

Linux sees this as a long delay when unbinding the nvme device.
Eventually the interrupt timeout occurs and it continues.
To fix this we ensure we deassert the IRQ for a CQ when it is
