The hooked spdk_pci_device was being removed when someone
stopped using it (detached from it). The following didn't
work:
$ rpc.py bdev_nvme_attach_controller 10000:00:01.0
$ rpc.py bdev_nvme_detach_controller 10000:00:01.0
$ rpc.py bdev_nvme_attach_controller 10000:00:01.0
The second attach can't find PCI device 10000:00:01.0.
To fix it, simply don't do anything in VMD on device detach.
The entire callback will be removed soon. You don't get
notified when someone starts using your hooked device, so
there's not much gain from knowing when someone stops.
